Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure allows for selective modifications, making it valuable in constructing isoindoline-based compounds with potential neurological or anti-inflammatory activity. Commonly employed in cross-coupling reactions due to the bromo functional group, enabling the formation of carbon-carbon bonds in complex molecule assembly. Also utilized in medicinal chemistry research for building blocks in proteolysis-targeting chimeras (PROTACs) and other targeted therapies.
