Used as a catalyst in organic synthesis, particularly in selective oxidation reactions.

Employed in electroplating baths to improve the stability and conductivity of tin-based coatings, and in the metal industry as a flux to lower the melting point of impurities and prevent oxidation during welding or melting processes.

Serves as a fluorinating agent in the production of specialty fluoropolymers.

Applied in glass and ceramic manufacturing to enhance surface durability and chemical resistance.

Also utilized in analytical chemistry for the detection and separation of certain metal ions due to its ability to form stable complexes, and in laboratory research to study the properties of heavy metal fluoride compounds.
