Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of benzodiazepine derivatives and other central nervous system agents. It serves as a building block in organic synthesis due to the presence of both bromine and ester functional groups, enabling cross-coupling reactions and ring formation. Commonly employed in research settings for the preparation of fluorescent dyes and agrochemicals. Its structure allows for easy modification, making it valuable in medicinal chemistry for structure-activity relationship studies.
