Chloromethane CAS 74-87-3
Sinochem is a major Chloromethane supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Chloromethane.
Chloromethane (Methyl Chloride) is a colorless, flammable gas with a faint sweet odor. It is widely used as a refrigerant, methylating agent in chemical synthesis, and in silicone polymer production.
- Versatile Industrial Solvent – Effective in pharmaceuticals, silicone production, and rubber processing.
- High Reactivity – Useful as a methylating agent in organic synthesis.
- Cost-Effective Feedstock – Used in producing silicones, agrochemicals, and quaternary ammonium compounds.

Appearance: Colorless gas with a slightly sweet ether-like odor.
Water Solubility: Slightly soluble in water, soluble in ethanol, chloroform, benzene, carbon tetrachloride, glacial acetic acid, etc.
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: Because methyl chloride has an aroma, slow effect (delayed effect), weak irritation and anesthetic effects, the poisoned person cannot feel it even at dangerous concentrations, so chronic poisoning is common. Inhaling a small amount of vapor for a long time will cause chronic or subacute poisoning, from dizziness and drunkenness-like symptoms to loss of appetite, drowsiness, difficulty walking, movement failure, etc., and may also cause visual impairment. Inhaling a large amount of it will damage the myocardium. Contact with liquid methyl chloride can cause frostbite. When the symptoms are severe, convulsions, lethargy and death may occur. After poisoning, leave the scene immediately and receive emergency treatment.
