Used as a source of fluoride in organic synthesis, particularly in nucleophilic fluorination reactions. It is effective in replacing chloride or other halides with fluoride in pharmaceutical and agrochemical intermediates. Commonly employed in the preparation of radiopharmaceuticals, including PET imaging agents, due to its reactivity and stability when dried. Also utilized in the production of specialty glasses and ceramics where controlled fluoride release is required. Its spray-dried form enhances solubility and handling in anhydrous reactions.
