Chloroperbenzoic acid is a chemical compound with the formula C7H5ClO3. It is a colorless to pale yellow solid that is primarily used as an oxidizing agent in organic chemistry. This compound is particularly effective in the epoxidation of alkenes, converting them into epoxides, which are valuable intermediates in the synthesis of various chemicals. This acid is derived from benzoic acid and contains a peracid functional group. It is often used in laboratory settings and industrial applications for its ability to introduce oxygen into organic molecules. Safety precautions are necessary when handling chloroperbenzoic acid due to its reactive nature.
