Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for the preparation of heterocyclic compounds due to its reactive chloro and amide functional groups. Commonly employed in the synthesis of bioactive molecules, including antifungal and antimicrobial agents. Also utilized in polymer chemistry as a monomer or cross-linking agent to modify polymer properties. Its solution form enhances handling and reactivity in liquid-phase reactions.
