Used as a source of fluoride ions in organic synthesis, particularly in nucleophilic fluorination reactions where it helps replace other halogens with fluorine in pharmaceuticals and agrochemicals. Commonly employed in the preparation of fluorinated compounds due to its reactivity and availability. Acts as a catalyst or reagent in the synthesis of fluoroaromatics, which are key building blocks in drug development. Also utilized in metal plating processes, especially aluminum and steel, to improve surface finish and corrosion resistance. In analytical chemistry, it serves to mask interfering metal ions during tests. Applied in etching glass and removing oxides from metals in industrial settings. Its ability to form strong bonds with silicon makes it useful in decomposing silicates during sample preparation for analysis.
