Used as an oxidizing agent in chemical synthesis, particularly in organic reactions where selective oxidation of alcohols or glycols is required. Commonly employed in analytical chemistry for the detection and determination of manganese and other metals through colorimetric methods. Widely used in histology and pathology laboratories for periodic acid-Schiff (PAS) staining to identify glycogen, mucopolysaccharides, and other carbohydrates in tissue samples. Also utilized in electrochemistry and sensor development due to its stable redox properties. Suitable for use in environmental applications for the degradation of pollutants via advanced oxidation processes.
