Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure allows for selective functionalization in multi-step organic reactions, making it valuable in medicinal chemistry. Commonly employed in the preparation of peptide mimetics and labeled compounds for research due to the stability of the Boc-protected amine group and the reactivity of the naphthol moiety. Also utilized in the production of specialty dyes and fluorescent probes, where the aromatic scaffold contributes to light absorption and emission properties.
