Methyldichlorophosphine (alternatively known as dichloro(methyl)phosphane and methyl phosphonous dichloride) is an organophosphorus compound with the chemical formula CH₃Cl₂P. It is a colorless, corrosive, flammable, and highly reactive liquid with a pungent odor. It is also extremely toxic if inhaled, can cause burns upon contact with the skin and eyes, and releases fumes of hydrochloric acid in moist environments.^[1]

Methyldichlorophosphine belongs to the group of halophosphines, which are used as intermediates in the production of plant protection agents, stabilizers for plastics, and catalysts. It is a precursor of the herbicide Glufosinate. It is also used in the production of flameproofing compounds.^[2]

Methyldichlorophosphine has a number of potential uses, but it is often used in the manufacture of nerve agents. When reacted with sulfuryl chloride it produces methylphosphonic acid dichloride, a direct chemical precursor to the nerve agents sarin, soman, and VX.^{[citation needed]}
