Use
Methyldichloroarsine. is a reducing agent. Reacts rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Can ignite on contact with alcohols. Incompatible with acids, alcohols, amines, and aldehydes. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. In one instance, reaction with chlorine rapidly produced gaseous chloromethane, which led to an over pressurization failure [J. Chem. Soc., Dalton Trans., 1976, 1479].
