A-232
Chemical compound
From Wikipedia, the free encyclopedia
A-232 is an organophosphate nerve agent.[1] 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.[2][3][4]

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 is identified (by its IUPAC name) as a specific example for the group of compounds circumscribed at 1.A.14 in the schedule.[5][6] 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.
