Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of chiral compounds where stereochemistry plays a critical role in biological activity. Its functional groups—hydroxyl, chloro, and isoindoline dione—allow for selective chemical modifications, making it valuable in constructing complex molecules. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) that require high enantiomeric purity. Also utilized in research settings for asymmetric synthesis and in the design of novel bioactive molecules.
