Methyl chloride

Methyl chloride (CAS 74-87-3), also known as R-40, is a compressed liquefied gas used as a methylating agent and chemical intermediate across multiple industrial sectors. It serves as a key building block in the synthesis of silicones and agricultural chemicals. In polymer manufacturing, it is the primary methylating agent in the production of methylcellulose and other cellulose ethers. These materials are used as thickeners, binders, and film formers in various industrial applications.

The silicone industry relies on this chemical to produce chlorosilane intermediates. This represents the foundational step in manufacturing silicone fluids, resins, and elastomers used in global manufacturing and construction. In agrochemical synthesis, it functions as a methylating reagent for producing herbicides and plant growth regulators. Pharmaceutical manufacturers also use it as a reaction solvent and intermediate in the synthesis of active ingredients.

Methyl chloride is supplied as a liquefied gas under pressure, typically in cylinders, drums, or ISO tank containers for bulk orders. It is available in technical and high-purity grades to meet specific requirements. These grades are designed for both industrial synthesis and more demanding pharmaceutical or specialty chemical applications. Purity specifications and packaging configurations vary by supplier and specific end-use requirement.
