Chlorosoman is a chlorine analog of soman.

It is a highly toxic organophosphorus compound and used as the precursor substance for soman nerve agent.

Soman is insoluble in water, with a boiling point of 223 degrees Celsius and a melting point of -27 degrees Celsius.

ClGD follows the same synthetic route as soman, with fluoridation being omitted.

Chlorosoman is prepared by the Finkelstein reaction between a solution of sodium chloride in DMF and soman.
