Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anticonvulsant and antimicrobial agents. It serves as a building block for heterocyclic compounds due to its reactive carbonyl and amine groups. Commonly employed in the preparation of indole-based derivatives, which show biological activity in medicinal chemistry. Also utilized in agrochemical research for designing novel pesticides and herbicides. Its halogen substituents allow for further functionalization via cross-coupling reactions, making it valuable in organic synthesis and drug discovery.
