Used in peptide synthesis as a protected dipeptide building block. The tert-butoxycarbonyl (Boc) group serves as an amine protecting group, allowing selective deprotection and coupling in stepwise peptide assembly. The benzyl ester acts as a carboxyl protecting group, which can be removed under mild conditions, such as hydrogenolysis, without affecting other sensitive functional groups. This compound is particularly useful in the preparation of complex peptides and peptidomimetics for pharmaceutical research, including enzyme inhibitors and bioactive molecule development. Its stability and selective reactivity make it valuable in solid-phase and solution-phase peptide synthesis.
