Chlorosoman is a
chlorine
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is ...

nerve agent
Nerve agents, sometimes also called nerve gases, are a class of organic chemicals that disrupt the mechanisms by which nerves transfer messages to organs. The disruption is caused by the blocking of acetylcholinesterase (AChE), an enzyme that ...
. 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. Chlorosoman is at least 2.5x less toxic than its analogue.
The ClG series of compounds is used more as a precursor to highly toxic compounds. For example, soman is a precursor to
EA-2613
EA-2613 is an extremely toxic organophosphate nerve agent. It's an extremely potent acetylcholinesterase inhibitor that is resistant to atropine and oxime treatment.

Synthesis
ClGD follows the same synthetic route as soman, with fluoridation being omitted. Chlorosoman is prepared by the
Finkelstein reaction
The Finkelstein reaction named after the German chemist Hans Finkelstein, is an SN2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an equilibrium reaction, but the rea ...
