Dicyclohexyl phosphorofluoridate

Dicyclohexyl phosphorofluoridate (DCFP),[1] also known as TL-941 or T-1840,[2] is an extremely toxic organophosphorus compound with powerful anticholinesterase action. It's a colorless liquid that is extremely resistant to hydrolysis.[3] DCFP can be produced by reaction of cyclohexanol with phosphoryl dichloride fluoride.[2][3]
