A Novichok agent (Russian: Новичо́к, "newcomer", "novice", "newbie") is one of a group of seven binary chemical weapons developed at the GosNIIOKhT state chemical research institute by the Soviet Union and Russia between 1971 and 1993. Some Novichok agents at STP are solids while others are liquids. It is thought that dispersal for the solids is possible by ultrafine powder.
Russian scientists who developed the nerve agents claim they are the deadliest ever made, with some variants possibly five to eight times more potent than VX, and others up to ten times more potent than soman. As well as Russia, Novichok agents have been known to be produced by scientists "in several NATO member states" and Iran.
In the 21st century, Novichok agents came to public attention after they were used to poison opponents of the Russian government, including the Skripals and two others in Amesbury, UK (2018) and Alexei Navalny (2020).

По формуле это получается ближайший родственник малоизвестного американского БОВ GV.
GV (IUPAC name: 2-(Dimethylamino)ethyl N,N-dimethylphosphoramidofluoridate) is an organophosphate nerve agent. GV is a part of a new series of nerve agents with properties similar to both the "G-series" and "V-series". It is a potent acetylcholinesterase inhibitor with properties similar to other nerve agents, being a highly poisonous vapour. Treatment for poisoning with GV involves drugs such as atropine, benactyzine, obidoxime, and HI-6.

Отличается от него только тем, что фтор замещен этокси группой. Так что можно смело американцам предъявлять, что они хайли лайкли российских граждан своим химическим оружием травят через агента Ринка, иначе бы откуда он производное американского нервно-паралитического газа взял
