In this short note I describe why the chemical forensic analysis and logic described in the French Intelligence Report of April 26, 2017 (FIR) could lead to a high confidence conclusion that an indigenous nerve agent attack in Denver, Colorado was perpetrated by the Syrian government.
Such an obviously flawed investigative finding would be a product of the same combination of irrational arguments and unsound scientific evidence that the FIR used as its basis to reach a conclusion that the Syrian government must have executed in nerve agent attack on April 4, 2017 in Khan Sheikhoun.
We start from quoting directly from page 2 of the French intelligence report, which can be found in a PDF file at :
France therefore independently and categorically confirms that sarin was used on 4 April. The United States, the United Kingdom, Turkey and the Director-General of the OPCW have also established that sarin was employed on the basis of analysis of biomedical samples.
- c) According to the intelligence obtained by the French services, the process of synthesizing sarin, developed by the Scientific Studies and Research Centre (SSRC) and employed by the Syrian armed forces and security services, involves the use of hexamine as a stabilizer. DIMP is also known as a by-product generated by this process.
- d) This intelligence on the process used by the regime, which is a sign of its responsibility in the attack on 4 April, is based notably on the analysis of the content of an unexploded grenade which was used with certainty by the Syrian regime during the Saraqib attack on 29 April 2013.
Aside from the lack of a rational linkage of asserted observations, the FIR falsely claims (or implies that) the presence of DIMP is a unique indicator that the sarin found by the French at Saraqib must have been produced by the Syrian government. As it turns out, DIMP is likely to be found at any location where sarin has been introduced into the environment. In the case of hexamine, this chemical can be produced by the military explosives in a sarin nerve agent dispensing munition or from explosives produced in military attacks unrelated to the use of sarin.
The diagram on the next page below shows the path from sarin that leads to DIMP.
Sarin is a complex unstable molecule that can easily be disrupted by impurities contained in the final product. It is commonly produced by mixing a complex and difficult to produce chemical known as DF with isopropyl alcohol. The chemical reactions that produce sarin also produce hydrogen fluoride, a powerful and highly corrosive acid. In order to remove the hydrogen fluoride produced along with the sarin, a “fluorine scavenging agent” is mixed with the isopropyl alcohol when the two binary components are combined. The component that is typically used as a fluorine scavenger is isopropyl amine. The isopropyl amine does not play a role in producing sarin, its purpose is simply to chemically bond with the fluorine ions in the simultaneously produced hydrogen fluoride.
Another chemical that is capable of scavenging fluorine from the hydrogen fluoride is hexamine. Hexamine is a solid and is relatively insoluble in isopropyl alcohol – but if it is mixed with decaying sarin, it can remove
the single fluorine atom that is attached to sarin molecules. Figure 1 below shows a structural diagram that indicates the sequence of processes that could lead to the production of DIMP.

The sequence of steps that result in sarin being transformed into DIMP which FIR implies is a unique signature associated with sarin produced by the Syrian government. In fact, DIMP could easily be produced in many circumstances from the normal breakdown of sarin after its use.

The point that DIMP is an expected product to be found in the aftermath of a sarin attck is made in a statement from United States Agency for Toxic Substances and Disease Registry (ATSDR) which is an arm of the Center for Disease Control (CDC). The ATSDR document that describes DIMP can be found at https://www.atsdr.cdc.gov/ToxProfiles/tp119-c1-b.pdf.
We quote from this document below:
Diisopropyl methylphosphonate, or DIMP, is a chemical by-product resulting from the manufacture and detoxification of GB (also called Sarin), a nerve gas that the Army produced from 1953 to 1957. … You might find diisopropyl methylphosphonate in places where GB has been produced, stored, or used, for example, the Rocky Mountain Arsenal (RMA) outside of Denver, Colorado.
It is therefore clear that if the FIR analysis that led to the identification of sarin as being produced by the Syrian government would have led to the same unsupported conclusion from the FIR if it were applied to an indigenous sarin attack in Denver Colorado.
This would particularly be the case if a sarin dispersing munition similar to the one described by FIR in the sarin nerve agent attack of April 29, 2013 was used in the postulated indigenous attack. That particular munition had a small charge of military explosives to rupture the container and disperse the sarin. The explosive would have certainly produced hexamine as a byproduct. The hexamine could have readily broken the fluorine bonds on some of the sarin residue leading to the production of DIMP. However, this is not the only path for producing DIMP the residues from a sarin attack.

It’s now 2017 – since 2001 the NATO western governments and their intelligence services have been coming up with ‘reports’ about ‘nerve agents and crazed middle eastern dictators’ to tailor fit the western political initiatives, of aggressive military action against, and ultimate political reconfiguration of, non US-Israel compliant middle eastern states. How long do these western politicians and senior bureaucrats think the public will keep on listening to exactly the same fraudulent narrative?
As long as it won’t bite them in the butt, they won’t care … public is occupied with much more important stuff, like tv, food, vacation etc etc
As long as Assad denies abortion rights, I won’t care.
Same dumb-assed logic used in Ghouta. It’s like a bad tag-team wrestling match: one ‘coalition’ crony handing off flawed evidence/data to another for self-referencing confirmation that Assad did it even though the idea defies all rational thought. In true psychopath form, they used the same false-flag again, but goaded Trump into acting before anyone could convince him he was being cucked.
Ghouta used the UN OPCW (CW inspectors) and UK’s Porton Down lab. Not to prove anything, but to confuse the issue and merely suggest that the evidence showed Assad did it to America’s knuckle-dragging leader’s satisfaction. Not that any American leaders actually believed the carefully-crafted ‘evidence’, but they figured it was enough to fool the stupid American people. As much as Obama wanted to go after Assad, even he thought the case was too flimsy and backed off.
Now we have France stepping in as the new crony stooge, attempting to use the same flawed argument that Assad did it because their labs found hexamine. Never mind that 1) they can’t say for certain if Syria EVER used hexamine in their old CW program (they merely suggest it), and 2) even if Syria DID use hexamine, then western intel is going to supply hexamine-laced Sarin to the head-choppers for a false flag.
The US intends to use the UN the same way it does for nuke program inspections: 1) make someone give up their nukes, 2) constantly accuse them of violating the treaty over and over and over again, 3) re-apply the sanctions lifted when they gave up their nukes, 4) false flag as casus belli to attack them and kill their leader.
Can anyone see ANYTHING different here between the Kill Ghadaffi UN scheme or the Kill Hussein UN scheme? Psychopaths keep reusing the deceptions that worked in the past. They’re lazy and they figure people will keep buying the exact same lies.
I also read this report at Col. Lang’s Sic Semper Tyrannis. To paraphrase (and do correct me if I am wrong …)
1. Hexamine is an explosive agent, not a stabilizer. DIMP is not unique to Syrian production.
2. The Syrians used binary weapons, not single weapons with stabilizers.
Postol is not exonerating the Syrian govt, just pointing out that the French did not prove anything.
I’d like to add that however flawed, the French Intelligence Report was a work of art compared to the pile of dog poo that my govt produced. I’m embarrassed by what we wrote and alarmed that the MSM didn’t even question it a little. I’m scared. We are lost and have no way of finding our way back to sanity.
From what I read on the subject, I believe Hexamine can be used both as a stabilizer for unary sarin and as an acid scavenger when finally mixing the components of binary sarin. But this second usage for hexamine is not documented and likely not even recorded before in military sarin production. Like Postol said, the acid scavenger role is usually played by isopropyl amine.
Hexamine is also a pretty common chemical that has many industrial and military applications (including for example, the preservation of paint).
That’s why its presence is hardly a smoking gun. In East Ghouta, inspectors found samples containing both sarin and hexamine but also samples containing only hexamine, with no salts that could suggest that the sarin had evaporated. It’s not even possibile to say with certainty that the sarin and the hexamine were actually associated: they may have come from different sources.
