Chlorosoman is a chlorine analog of soman. It is a highly toxic organophosphorus compound and used as the precursor substance for soman nerve agent. [2] Its physical properties are estimated. Soman is insoluble in water, with a boiling point of 223 degrees Celsius and a melting point of -27 degrees Celsius.
