A-262 is an
Novichok agents that were revealed by Vil Mirzayanov. Mirzayanov gives little specific information about A-262, stating that it is highly toxic, but no figures are given to compare it to other related agents. It is reportedly a solid rather than a volatile liquid as with most nerve agents, and in order to weaponise it successfully, it had to be milled into a fine powder form that could be dispersed as a dust.[1]
Legal status
A-262 is not specifically listed in the Annex on Chemicals of the Chemical Weapons Convention, and falls outside the general definitions covering other Novichok agents, even though it has a chemical structure similar to that of both A-232 (the example compound for schedule 1.A.14) and A-242 (the example compound for schedule 1.A.15). It would however be considered a "Toxic Chemical" under the catch-all provisions due to its potent acetylcholinesterase inhibitor activity and potential military applications, but the level of control it is subject to is lower than that for compounds specifically listed under Schedule 1.[2]
