Chlorosarin is a chemical precursor used in the final step of one method for the production of the nerve agentsarin. Also known asO-isopropyl methylphosphonochloridate and isopropyl methylphosphonic chloride, it has amolecular weight of 156.55 g/mol and a molecular formula ofC4H10ClO2P.
Chlorosarin will produce effects similar to those of sarin if it is absorbed into body, but they are less severe. However, like sarin, it is highly toxic and small doses of it would be lethal. TheChemical Weapons Convention also lists chlorosarin as well as other chemicals suchchlorosoman andQL as controlled substances inSchedule 1.[1]
Like GB, ClGB presents a varied preparation route. Overall, it is a lower cost chemical warfare agent than sarin. ClGB was one of the final intermediates of step five of the DMHP process, being known as a raw impurity and as a final precursor.[2]
Chlorosarin can be synthesized fromdiisopropyl methylphosphonate (DIMP) andphosgene.
