DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes commonly in paint removers. [12] In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings.

Dichlorocarbene is an intermediate in the carbylamine reaction.In this conversion, a dichloromethane solution of a primary amine is treated with chloroform and aqueous sodium hydroxide in the presence of catalytic amount of the phase-transfer catalyst.
The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.

In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon-to-carbon double or triple bonds), phenols and anilines.. An unknown sample is treated with a small amount of elemental bromine in an organic solvent, being as dichloromethane or carbon tetrachloride.
