Product Details

Dichloromethane is a colorless liquid with an ethereal, but penetrating odor. Its miscibility in alcohol and ether and slight solubility in water has made it an ideal solvent and otherwise extremely versatile chemical. It has been used industrially (solvent and paint remover), as a drug (inhalation anesthetic) and as an agricultural chemical (growth regulator and fertilizer). It is narcotic in high concentrations and carcinogenic. Inhalation exposure to this substance irritates the nose and throat and affects the central nervous system.

Product Application Of Dichloromethane CAS#75-09-2

Methylene chloride is primarily used as a paint remover solvent. It is also used as an aerosol propellant, processing solvent in the production of steroids, antibiotics, vitamins, and tablet coatings. Additionally, it serves as a degreasing agent, particularly in electronics manufacturing. Methylene chloride is utilized as a urethane foamblowing agent as well. It finds application in metal cleaning, production of polycarbonate resins and triacetate fibers, film processing, ink formulations, and as an extraction solvent for spice oleoresins, caffeine, and hops. Due to its high volatility, it is commonly employed as a solvent in various extraction processes. Methylene chloride possesses strong solvent power for cellulose esters, fats, oils, resins, and rubber. It is more soluble in water compared to other chlorinated solvents. In the past, it was approved for use as an insecticide for commodity fumigation of strawberries, citrus fruits, and grains.
