Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active agents. Its structure allows for the introduction of specific halogen and amino functionalities that enhance binding affinity and metabolic stability in final drug compounds. Commonly employed in multi-step organic syntheses where regioselective substitution is required. Also utilized in the preparation of agrochemicals and bioactive molecules due to its reactive functional groups that facilitate further chemical modifications.
