Mipafox is a highly toxic organophosphate insecticide that is an irreversible acetylcholinesterase inhibitor and is resistant to cholinesterase reactivators.[1] It was developed in the 1950s and is now believed to be no longer in use.[2]

Toxicity

There are case reports of delayed neurotoxicity and paralysis due to acute exposure to mipafox.[3]

Synthesis

Phosphoryl chloride is first reacted with isopropylamine. The resulting product is then reacted with potassium fluoride or ammonium fluoride to produce mipafox.[4]
