Methylene Chloride
CH₂Cl₂ | CAS: 75-09-2 | HS: 29031200
Product Description
Methylene Chloride (Dichloromethane, DCM) is a versatile polar aprotic solvent prized for its exceptional solvency power, low boiling point (39.6°C), and non-flammability. It is one of the most widely used industrial solvents in pharmaceutical manufacturing — serving as an extraction solvent, reaction solvent, and recrystallisation medium in API synthesis — and in food processing for coffee and tea decaffeination. Its low boiling point enables efficient solvent recovery by distillation, making it economical in closed-loop operations. MITCHEM supplies technical, pharmaceutical-grade (ICH Q3C Class 2 compliant), and food-grade DCM for regulated end-use applications.
Applications by Industry
Primary extraction and reaction solvent in API synthesis, polymer dissolution, and recrystallisation; ICH Q3C Class 2 designation requires residual solvent testing in finished drug products.
Active ingredient in industrial paint strippers for aircraft maintenance, architectural restoration, and metal fabrication; penetrates and swells cured coatings for mechanical removal.
Food-grade DCM is used in the direct solvent decaffeination process for coffee and tea; selectively extracts caffeine while leaving flavour compounds intact; residual limits regulated by FDA/EFSA.
Used as a blowing agent in polyurethane foam production and as a solvent in contact adhesives, polysulphide sealants, and cellulose acetate fibre spinning.
