Used as an intermediate in pharmaceutical synthesis, particularly in the preparation of bioactive molecules and drug candidates. Its structure allows for further functionalization, making it valuable in constructing isoindoline-based compounds with potential neurological or anti-inflammatory activity. Commonly employed in research settings for developing proteolysis-targeting chimeras (PROTACs) and kinase inhibitors due to its ability to serve as a building block for complex heterocyclic systems. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving cereblon E3 ligase modulators.
