Chloromethane CAS 74-87-3
Chloromethane (CH3Cl), universally referred to as Methyl Chloride, is a highly reactive, colorless, and liquefied flammable gas characterized by a faint ether-like sweet odor. As a pivotal C1 building block and critical chemical intermediate, it serves as the foundation for the silicone polymer industry, chemical synthesis, and pharmaceutical manufacturing. Engineered under stringent synthesis and liquefaction controls, our premium-grade Chloromethane guarantees ultra-low moisture and acid content, delivering exceptional yield efficiency as a powerful methylating agent for global downstream manufacturers.
- Versatile Industrial Feedstock: Highly effective as a core intermediate in pharmaceutical synthesis, silicone rubbers, methyl chlorosilanes, and butyl rubber processing chains.
- Exceptional Methylating Reactivity: Optimized for maximum chemical conversion rates when introducing methyl groups into organic matrices and quaternary ammonium compounding.
- Cost-Effective Critical Intermediate: Serves as a highly reliable, high-yield scalable precursor for producing advanced silicones, specialized agrochemicals, and surfactants.

Properties: Colorless gas, can be compressed into a colorless liquid with ether smell and sweet taste, has anesthetic effect, flammable. Good thermal stability (below 400℃, does not react with metals). Slightly soluble in water, soluble in ethanol, benzene, carbon tetrachloride, miscible with chloroform, ether and glacial acetic acid. Corrosive to aluminum, magnesium and zinc.
Storage: Store in a cool, ventilated toxic gas warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 30°C. Store separately from oxidants and do not mix them. Use explosion-proof lighting and ventilation facilities. Do not use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.
Safety Protection: Classified as a hazardous flammable and toxic gas (Class 2.1, UN 1063). Exposure can induce acute central nervous system depression and systemic toxicity. Avoid all inhalation of vapors and direct skin contact with liquefied gas, which causes severe frostbite. Operators must wear positive-pressure self-contained breathing apparatus (SCBA), chemical-resistant antistatic clothing, and specialized thermal/chemical protective gloves. Ensure the facility is equipped with automated gas leakage detection systems and emergency scrubbing equipment.

Chloromethane Applications
Chloromethane CAS 74-87-3 is a fundamental alkylating reagent extensively leveraged across the following core industrial sectors:
- Silicone Macromolecule Production: Serves as the primary, irreplaceable raw material for manufacturing methyl chlorosilanes (including dimethyldichlorosilane), which are the essential building blocks for silicone rubbers, fluids, resins, and sealants.
- Cellulose Modification: Extensively utilized as an etherifying agent in the production of methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC), upgrading water retention and rheological performance in construction chemicals.
- Specialty Polymers & Rubber Synthesis: Deployed as a highly efficient process solvent and catalyst carrier in the low-temperature polymerization of butyl rubber and high-performance isobutadiene rubber compounds.
- Agrochemical & Surfactant Fine Synthesis: Functions as a critical methylating intermediate for formulating advanced crop protection herbicides, systemic pesticides, and quaternary ammonium cationic surfactants.
