Dichloromethane is a clear liquid with low viscosity at room temperature and has a high index of refraction (1.4244) giving it a shiny appearance. It has a sweet smell similar to that of chloroform. Dichloromethane is quite volatile, and boils at only 39.6 °C (103.3 °F), not far above human body temperature.
Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent.
