Used as a catalyst in organic synthesis, particularly in oxidation reactions where selective transformation of substrates is required. It serves as a source of trivalent chromium in electroplating baths, contributing to the formation of corrosion-resistant and wear-resistant coatings. Employed in research laboratories for the preparation of other chromium-containing compounds and coordination complexes. Its hygroscopic nature makes it suitable for use in moisture-controlled chemical reactions. Also utilized in certain solid propellant formulations due to the oxidizing nature of the perchlorate ion, supporting combustion in specialized aerospace applications.
