Used primarily in pharmaceutical research as a key intermediate in the synthesis of benzodiazepine derivatives. These compounds are known for their central nervous system depressant effects, including anxiolytic, sedative, muscle relaxant, and anticonvulsant properties. The carboxylic functional group allows for further chemical modification, enabling the development of novel analogs for drug discovery. It is not used directly as a therapeutic agent but serves an important role in the preparation of active pharmaceutical ingredients targeting neurological and psychiatric disorders.
