m-Chloroperbenzoic acid (m-CPBA) is a chemical compound commonly used as an oxidizing agent in organic chemistry. It is a peracid derived from benzoic acid and contains a chlorine atom at the meta position. m-CPBA is particularly useful for converting alkenes into epoxides, which are important intermediates in the synthesis of various organic compounds. This compound is typically a white crystalline solid and is soluble in organic solvents. Due to its strong oxidizing properties, m-CPBA must be handled with care, as it can react vigorously with certain substances. It is widely utilized in laboratories for various chemical transformations.
