Used in dentistry as a caries preventive agent due to its ability to release fluoride ions that strengthen tooth enamel. Also employed in organic synthesis as a fluorinating agent, particularly for replacing halogens or oxygen-containing groups with fluorine. Finds use in materials science for preparing fluoride-doped coatings and in electrochemistry as a component in certain types of batteries. Its antimicrobial properties make it suitable for use in some medical devices and wound care products.
