CAS 74-87-3
Overview
Methyl chloride (chloromethane, CH3Cl) is a gaseous chlorinated methane supplied in refillable cylinders and tank quantities. Our enterprise special grade reaches 99.98% purity. It is the principal raw material for organosilicon monomers and methyl cellulose, and a high-purity methylating agent for chemical synthesis.
