This substance is used by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. State-of-the-art processes to directly convert methane into CH3Cl are run under corrosive conditions and typically yield a mixture of chloromethanes requiring subsequent separation. Chloromethane is composed of a single carbon atom bound to three hydrogen atoms and one chlorine atom.
