Used primarily as a strong oxidizing agent in chemical synthesis and industrial processes. Commonly applied in polymerization reactions as an initiator, especially in the production of emulsion polymers like synthetic rubber and latex. Also utilized in environmental testing to digest organic matter in water and wastewater samples, enabling the measurement of total phosphorus and nitrogen. Its high oxidative capacity makes it suitable for cleaning and etching applications in electronics manufacturing, particularly in printed circuit board processing. Additionally, employed in some dental and medical applications for bleaching and surface treatment due to its ability to break down organic compounds.
