Used primarily as an oxidizing agent in organic synthesis, especially for epoxidation of alkenes and oxidation of ketones to esters via the Baeyer-Villiger reaction. It is effective in converting amines to N-oxides and sulfides to sulfoxides or sulfones, making it valuable in pharmaceutical and fine chemical manufacturing. Its solid form and relative stability allow for easier handling compared to other peracids, suitable for lab-scale and industrial applications. Commonly employed in the synthesis of complex molecules where selective and controlled oxidation is required.
