Product Description
Methylene Chloride (DCM) is a volatile, nonflammable liquid with a faint, sweet, chloroform-like odor. It is slightly soluble in water (1.38 g/100 mL at 20°C) but fully miscible with ethanol, ether, and most organic solvents. DCM is non-corrosive, pH-neutral, and chemically stable under normal conditions. Its low boiling point, high solvency power, and resistance to flammability make it ideal for industrial applications requiring rapid evaporation and minimal residue.
