Dichloromethane – DCM

Dichloromethane (DCM or methylene chloride) is the organic compound with the formula CH2Cl2. This colourless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents. It was first prepared in 1840 by the French chemist Henri Victor Regnault, who isolated it from a mixture of chloromethane and chlorine that had been exposed to sunlight.
