Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of angiotensin II receptor antagonists for treating hypertension. Its structure allows for selective modification in multi-step organic reactions, making it valuable in creating complex drug molecules. Commonly employed in peptide coupling and solid-phase synthesis due to the presence of both carboxylic acid and protected amine functional groups. The Boc-protected amine ensures controlled reactivity, enabling sequential deprotection and coupling steps in medicinal chemistry research.
