Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its structure supports the development of nitrogen-containing heterocycles, which are common motifs in drug design. The tert-butyl carbamate (Boc) group provides protection for the amine functionality during multi-step syntheses, allowing selective reactions at other sites in the molecule. The benzyl group can be removed or modified under mild conditions, making this compound valuable in peptide synthesis and the construction of complex amines. It is also employed in the development of chiral auxiliaries and catalysts due to the stereochemical features of the imidazolidine ring.
