Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates targeting central nervous system disorders. Its structure supports the construction of isoindoline-based scaffolds, which are found in compounds with potential neuroprotective, anti-inflammatory, and anticancer properties. Commonly employed in medicinal chemistry for derivatization and ring modification to enhance drug potency and metabolic stability. Also utilized in the preparation of proteolysis-targeting chimeras (PROTACs) due to its favorable functional group compatibility and stability.
