meta-Chloroperoxybenzoic acid (mCPBA) is a peroxy acid with chemical formula C7H5ClO3.
mCPBA is a strong oxidizing agent that may cause fire upon contact with flammable material. As a pure substance, it can be detonated by shock or by sparks. It is therefore sold commercially as a much more stable mixture that is about 75% mCPBA with the balance being 3-chlorobenzoic acid and water.
mCPBA is used widely as a reagent in organic chemistry to carry out a variety of chemical transformations. It is often preferred to other peroxy acids because of its relative ease of handling. The main areas of use are the conversion of ketones to esters (Baeyer-Villiger oxidation), epoxidation of alkenes, oxidation of sulfides to sulfoxides and sulfones, and oxidation of amines to produce amine oxides.
