Description

Methyl Chloride CAS NO 74-87-3 is a versatile chloromethane compound, also known as chloromethane, serving as a fundamental building block in organic synthesis. Its primary value lies in its role as a methylating agent and a key intermediate for producing silicones, agricultural chemicals, and pharmaceuticals. This product is essential for manufacturers in the chemical, agrochemical, and pharmaceutical industries requiring a reliable, high-purity feedstock.

Application

• Silicone Polymer Production: A primary feedstock for the synthesis of methylchlorosilanes, the precursors to silicone rubbers, resins, and fluids.
• Methylating Agent: Used in organic synthesis to introduce methyl groups into various compounds, including pharmaceuticals and fine chemicals.
• Agrochemical Manufacturing: Serves as an intermediate in the production of herbicides, insecticides, and other crop protection agents.
• Quaternary Ammonium Compounds: Employed in the manufacture of quats used as surfactants, disinfectants, and fabric softeners.
• Refrigerant & Propellant: Historically used as a refrigerant (R-40) and aerosol propellant, though its use has declined due to environmental and safety regulations.
• Solvent Applications: Utilized as an extraction solvent in the pharmaceutical and chemical processing industries.
• Butyl Rubber Production: Acts as a catalyst solvent in the polymerization process for butyl rubber.
• Laboratory Reagent: Used in research and development for methylation reactions and as a reference standard.

Quality Control

Our Methyl Chloride is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical testing, including gas chromatography (GC) for purity and impurity profiling, to meet the exacting standards of industrial and fine chemical synthesis. A Certificate of Analysis (COA) detailing all specifications is available with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature under ambient conditions, it must be stored in approved pressurized cylinders or tanks in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed and upright. Store separately from incompatible materials such as strong oxidizers and active metals.
