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.
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.

Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. log 10 of Methyl Chloride vapor pressure. Uses formula: ...
The US Environmental Protection Agency finalized a rule Tuesday that will end many uses of the highly toxic, cancer-causing solvent methylene chloride. The chemical will still be available for ...
[15] [16] The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol" (which since 1892 is called "methanol"). Methyl is the IUPAC nomenclature of organic chemistry term for an alkane (or alkyl) molecule, using the prefix "meth-" to indicate the presence of a single carbon.
The American Chemistry Council, the industry’s top lobbying group, describes methylene chloride as “an essential compound” used to make many products and goods that Americans rely on every ...
Chloromethyl methyl ether (CMME) is an ether with the formula C H 3 OCH 2 Cl. It is used as an alkylating agent and industrial solvent to manufacture dodecylbenzyl chloride, water repellents, ion-exchange resins, polymers, and as a chloromethylation reagent.
Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...
