Widely used as an oxidizing agent in organic synthesis, particularly for epoxidation of alkenes, oxidation of ketones to esters (Baeyer-Villiger oxidation), and conversion of amines to N-oxides. It is effective under mild conditions and commonly employed in the pharmaceutical industry for constructing complex molecules. Its solid form makes it easier to handle compared to other peracids, and it is often used in reactions where selectivity and controlled oxidation are important. Also utilized in the preparation of fine chemicals and intermediates where oxygen insertion is required.
