A-232 is an
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 it has been explicitly named as an example compound for schedule 1.A.14.[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. 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.
