Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

The original product, up to circa 2006, came in two versions - "All Purpose" and "Master Craftsman". The active and main ingredient of both the original Nitromors versions was dichloromethane (also known as methylene chloride) accompanied by a smaller proportion of methanol. This product was recommended by the Guild of Master Craftsmen and the ...
Despite the similar names, the anaesthetic mixture named "bichloride of methylene" did not contain the actual compound that would be called bichloride of methylene (Dichloromethane CH 2 Cl 2). Instead, it was later discovered as a mixture of chloroform and alcohol marketed as the bichloride of methylene and even given the formula CH 2 Cl 2. [12]

Some haloalkanes are still widely used for industrial cleaning, such as methylene chloride (dichloromethane), and as refrigerants, such as R-134a (1,1,1,2-tetrafluoroethane). Haloalkenes have also been used as solvents, including perchloroethylene (Perc, tetrachloroethene), widespread in dry cleaning, and trichloroethylene (TCE, 1,1,2 ...
Chloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula CH 3 Cl. One of the haloalkanes , it is a colorless, sweet-smelling, flammable gas.
According to the EPA, methylene chloride is known to cause a range of cancers, as well as neurotoxicity and liver damage, while direct exposure can lead to death. The agency has reported that at ...
A methylene bridge can also act as a bidentate ligand joining two metals in a coordination compound, such as titanium and aluminum in Tebbe's reagent. [1] A methylene bridge is often called a methylene group or simply methylene, as in "methylene chloride" (dichloromethane CH 2 Cl 2).
