This compound is primarily used in organic synthesis as a building block for the preparation of more complex molecules. It serves as a key intermediate in the development of pharmaceuticals, particularly in the synthesis of active pharmaceutical ingredients (APIs). Its tert-butoxycarbonyl (Boc) protecting group is valuable in peptide synthesis, where it safeguards the amine functionality during reactions, allowing selective deprotection when needed. Additionally, the isoindoline structure makes it useful in the design of compounds with potential biological activity, such as enzyme inhibitors or receptor modulators. Its carboxylic acid group further enables conjugation or derivatization, expanding its utility in medicinal chemistry and drug discovery.
