Is dichloromethane (CAS:75-09-2) an organic compound?
Dichloromethane (CH₂Cl₂, CAS Number 75-09-2), also known as methylene chloride, is a common volatile organic compound (VOC) frequently found in the indoor air where levels range from 2- 100 µg/m³.
What Are the Properties and Uses of dichloromethane (CAS:75-09-2)?
DCM is formed by substituting two hydrogen atoms in methane (CH₄) with chlorine atoms. It is slightly soluble in water but readily soluble in ethanol and ether. Under normal conditions, it is a non-flammable, low-boiling solvent; however, its vapor can form a weakly flammable mixture in high-temperature air. Because of its good solvency, it is often used as a safer alternative to highly flammable solvents such as petroleum ether and diethyl ether.
