Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where sulfonyl chloride groups act as key coupling agents. Its reactivity allows for the introduction of sulfonyl functionalities into larger molecules, enabling the formation of sulfonamides, which are common structural motifs in drugs targeting inflammation, infections, and central nervous system disorders. Also utilized in agrochemical synthesis for building complex molecules with enhanced biological activity. The presence of both cyano and fluoro groups enhances its utility in cross-coupling reactions and increases the electron-withdrawing character, improving reaction selectivity in heterocyclic constructions.
