It is used in solid-phase peptide synthesis bioconjugation and as a building block for pharmaceuticals like analgesics anti-inflammatories and neuroscience drugs.

The compound protects the amine during multi-step synthesis of bioactive peptides protease inhibitors PROTACs and receptor antagonists enabling regioselective modifications.

This bifunctional molecule (formula roughly CHNO) acts as a cyclic -disubstituted amino acid analog with the Boc group shielding the amine for selective reactivity at the carboxylic acid.
