Methylene Chloride, also known as dichloromethane (DCM), is an organic compound with the chemical formula CH2Cl2. It is a colorless, volatile, nonflammable liquid with a characteristic sweet odor. It is used mainly as a solvent for paint and varnish removers, aerosol sprays, and pharmaceuticals. Methylene chloride is also used in the manufacture of other chemicals, such as refrigerants, solvents, and pesticides.

Methylene chloride is a chlorinated hydrocarbon with a molecular weight of 84.93 g/mol, a boiling point of 39.6°C (103.3°F), and a density of 1.3297 g/cm3. It is miscible with water, alcohol, and most organic solvents, and has a low vapor pressure of 6.4 mmHg at 25°C (77°F). It has a high octanol/water partition coefficient of 100, indicating its high lipophilicity.

Methylene chloride is primarily used as a solvent in various industrial applications, including paint and varnish removal, paint stripping, adhesive removal, and degreasing. It is also used as a solvent for waxes, resins, oils, fats, and rubber, and for extraction of caffeine from coffee beans. It is also used for aerosol propellants, pharmaceuticals, and in the production of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).

Methylene chloride is classified as a human carcinogen by the International Agency for Research on Cancer (IARC). Inhalation of high concentrations of this chemical can cause central nervous system depression, which can result in death. Long-term exposure to methylene chloride can also cause reproductive and developmental effects. For these reasons, it is important to take appropriate safety measures when working with this chemical.
