Applications Isodimethoate is an isomer of Dimethoate (D460505), which is an organophosphate insecticide. Isodimethoate is present in usual pesticide formulations of Dimethoate that is anticholinesterase which disables cholinesterase, an enzyme essential for central nervous system function and thus is neurotoxic for humans. Isodimethoate reacts with human red blood cell acetylcholinesterase (AChE) rendering part of AChE making it non-reactivatable.
