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 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 ...
The most important is dichloromethane, which is mainly used as a solvent. Chloromethane is a precursor to chlorosilanes and silicones. Historically significant (as an anaesthetic), but smaller in scale is chloroform, mainly a precursor to chlorodifluoromethane (CHClF 2) and tetrafluoroethene which is used in the manufacture of Teflon.

“There is more information on the toxicity of methylene chloride and the levels at which it causes this toxicity,” she added. “This information as well as more recent information on how much ...
1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2.The two compounds are isomers, each being colorless liquids with a sweet odor.
Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
Trump's EPA pressured scientists to downplay potential harms of some chemicals, according to staffers and the EPA's inspector general. That’s at odds with RFK Jr.’s agenda.
The output of this process is a mixture of the four chloromethanes: chloromethane, methylene chloride (dichloromethane), trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). These can then be separated by distillation .
