Used as a reagent in organic synthesis, particularly in cyanation reactions where introduction of cyanide groups is required. It serves as a safe and stable source of cyanide ions in catalytic transformations, offering advantages over more toxic cyanide salts. Applied in pharmaceutical manufacturing for constructing nitrile-containing compounds, which are key intermediates in active pharmaceutical ingredients. Also utilized in coordination chemistry for preparing boron- and cyanide-based metal complexes with potential catalytic or material science applications.
