a-232 a-232 a-232 is an organophosphate nerve agent. it was developed in the soviet union under the foliant program and is one of the group of compounds referred to as novichok agents that were revealed by vil mirzayanov. a-232 is reportedly slightly less potent as a nerve agent compared to some of the other compounds in the series such as a-230 and a-234, having similar potency to the older nerve agent vr. however it proved to be the most versatile agent as it was chemically stable and remained a volatile liquid over a wide temperature range, making it able to be used in standard chemical munitions without requiring special delivery mechanisms to be developed. a-232 names iupac name methoxy-(1-(diethylamino)ethylidene)phosphoramidofluoridate identifiers cas number 2387496-04-8 3d model (jsmol) interactive image chebi chebi:140424 chemspider 64808786 y pubchem cid 132472360 inchi inchi=1/c7h16fn2o2p/c1-5-10(6-2)7(3)9-13(8,11)12-4/h5-6h2,1-4h3/b9-7+key: bbtxavjvsqsxhz-vqhvlokhna-n smiles ccn(cc)c(\c)=n\p(f)(=o)oc properties chemical formula c7h16fn2o2p molar mass 210.189 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references legal status a-232 has been added to schedule 1 of the annex on chemicals of the chemical weapons convention as of june 2020, and it has been explicitly named as an example compound for schedule 1.a.14. for chemicals listed in schedule 1, the most stringent declaration and verification measures are in place combined with far-reaching limits and bans on production and use. it is notable to say that annex 1 does not explicitly relate this structure to the name a-232, just add this particular structure to the prohibited compounds section.
