Dicyclohexyl phosphorofluoridate (DCFP),[1] also known asTL-941 orT-1840,[2] is an extremely toxicorganophosphorus compound with powerfulanticholinesterase action. It's a colorless liquid that is extremely resistant tohydrolysis.[3] DCFP can be produced by reaction ofcyclohexanol withphosphoryl dichloride fluoride.[2][3]
