This compound is primarily used in organic synthesis and pharmaceutical research. It serves as a key intermediate in the preparation of more complex molecules, particularly in the development of active pharmaceutical ingredients (APIs). Its structure, featuring both a tert-butoxycarbonyl (Boc) protecting group and a carboxylic acid functional group, makes it valuable for peptide synthesis and other multi-step chemical processes. The Boc group can be selectively removed under mild acidic conditions, allowing for further functionalization of the molecule. Additionally, its indoline core is often explored in the design of compounds with potential biological activity, such as enzyme inhibitors or receptor modulators. Its applications are mainly focused on medicinal chemistry and drug discovery.
