Used as a source of fluoride ions in organic synthesis, particularly in fluorination reactions where controlled release of fluoride is required. Serves as a mild fluorinating agent in the preparation of fluorinated pharmaceuticals and agrochemicals. Employed in electroplating baths to improve metal deposition efficiency and surface finish, especially in aluminum and magnesium alloy treatments. Acts as a catalyst or reagent in some polymerization processes and specialty chemical manufacturing. Its hydrate form enhances handling safety and solubility in aqueous systems compared to anhydrous versions.
