Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring functionalized aromatic and ester moieties. Its structure supports peptide coupling and selective deprotection reactions, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in research settings for designing drugs targeting central nervous system disorders and inflammatory conditions. Also utilized in the preparation of protease inhibitors and receptor modulators due to its ability to mimic amino acid frameworks.
