Used as a reagent in organic synthesis, particularly in reactions requiring a non-coordinating anion. Facilitates cationic reactions by providing a stable silver cation source. Commonly employed in halide abstraction and in the preparation of other tetrafluoroborate salts. Also utilized in electrochemical applications and as a catalyst or catalyst precursor in certain coupling reactions. Its solubility in polar solvents makes it suitable for homogeneous reaction conditions.
