Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and central nervous system agents. Its structure supports the creation of compounds with neurological activity, including potential antidepressants and neuromodulators. The amine functionality allows for salt formation and further derivatization, enhancing its utility in drug design. The tert-butyl ester serves as a protecting group for the carboxylic acid, enabling selective reactions at the free amine. Commonly employed in research settings for constructing complex organic molecules where a protected carboxylic acid and free amine group are required.
