The @OPCW report identifying perpetrators of CW use in Syria is out now: https://t.co/60Ft47kwRc https://t.co/KnKJ5BRKAS
Today, on the anniversary of the attack on Duma, we are releasing our new interactive web portal, making available our dataset of 345 chemical weapons attacks over the course of the Syrian war. We hope this will give a sense of the scale of the challenge.

Last year, the @OPCW updated its list of chemical warfare agents for the first time since the treaty was signed in 1993. Find out what happened in this article by @s_costanzi and me in the latest issue of #ArmsControlToday by @ArmsControlNow

@francis95641723 My pleasure
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt Any insights @blumscientific?
@francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt I am glad to hear that you find my tables of useful. The substituents don't need to be the same. Note that I just updated the figure.
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt It is unclear whether this is the correct interpretation of the entries, or if the entries should be interprered as featuring an alkylidene carbon with an R substituent that could be a hydrogen or an alkyl/cycloalkyl group up to 10 carbon atoms (for a total of 11 carbon atoms).
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt In my table, I show the alkylidene carbon as a fixed component of the structure, with an attached R group that could be a hydrogen or an alkyl/cycloalkyl group up to 9 carbon atoms (for a total of 10 carbon atoms, including the alkylidene carbon).
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt If that group were to be a hydrogen, the whole amidine substituent would fall apart.
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt Importantly, the alkylidene group (despite the way entries CWC 1A13 and 1A14 are written) cannot be a hydrogen either.
@blumscientific @francis95641723 @OPCW @OPCW_ST @gregkoblentz @RichardCupitt I updated the figure, to show that the dialkylamino R groups cannot be hydrogens.
@francis95641723 @s_costanzi @OPCW @OPCW_ST @gregkoblentz @RichardCupitt Authorative OPCW document: The dialkylaminogroup is (Cyclo)Alkyl (C1-C10) the other two are either H or (Cylco)Alkyl (C1-C10)
