Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. It serves as a protected amine building block in the development of bioactive molecules, leveraging the tert-butyl carbamate (Boc) group for controlled deprotection under mild acidic conditions. The phthalimide moiety enables efficient amine introduction via Gabriel synthesis or related methods, making it valuable in medicinal chemistry for constructing complex amine-containing structures. Commonly applied in the synthesis of drug candidates where selective functionalization and protection strategies are required.
