Used primarily in specialized chemical synthesis and research laboratories as a source of fluoride ions and as a reagent in the preparation of other fluorinated compounds. It finds application in the field of inorganic chemistry for the generation of reactive fluorinating agents. Due to its high fluorine content and reactivity, it may be employed in the development of catalysts or in the modification of materials requiring strong fluorination conditions. Its use is limited due to toxicity and environmental concerns, restricting it to controlled environments with strict safety protocols.
