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.

Another source of poisoning is exposure to the organic solvent dichloromethane, also known as methylene chloride, found in some paint strippers, [89] as the metabolism of dichloromethane produces carbon monoxide. [90] [91] [52] In November 2019, an EPA ban on dichloromethane in paint strippers for consumer use took effect in the United States. [92]
According to the CDC, as of 2020, levels that it is normal to be exposed to in drinking water are lower than levels known to cause health problems. [1] A small number of studies have examined the effects of low levels of bromodichloromethane on people, but most were also exposed to other chemicals, so it may not be the only cause of reported health problems.

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.
Dichloromethane is the most important halomethane-based solvent. Its volatility, low flammability, and ability to dissolve a wide range of organic compounds makes this colorless liquid a useful solvent. [2] It is widely used as a paint stripper and a degreaser.

A new trend gaining popularity among people trying to lose weight is microdosing the diabetes medication Ozempic. Experts weigh the pros and cons of the practice.
There is a fundamental difference between using heat and UV light to make dichloromethane. UV light is much easier to use and is less dangerous than heat. SchicagoS 18:20, 10 April 2012 (UTC) If you want to claim that this is an easier way to make dichloromethane, you will need to find a reliable source that reports this.
