Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its amino and ester functional groups allow for selective reactions, making it valuable in building complex molecules. Commonly employed in the synthesis of bioactive compounds, including drug candidates requiring spacer or linker segments. The tert-butyl protection group offers stability during reactions and can be easily removed under mild acidic conditions, enabling controlled stepwise synthesis. Also utilized in the development of polymers and specialty materials where tailored chain length and functional handles are needed.
