Used as a strong oxidizing agent in polymerization reactions, especially in the production of synthetic rubbers and plastics. Commonly applied in etching copper for printed circuit boards due to its ability to dissolve metal surfaces. Employed in hair bleaching and cosmetic formulations as an activator for color development. Utilized in environmental testing to digest organic matter in water samples for COD (chemical oxygen demand) analysis. Also serves as a cleaning and decontamination agent in industrial equipment due to its effective breakdown of organic residues.
