Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of thiazole-based drugs. Commonly employed in peptide coupling reactions due to the presence of both carboxylic acid and protected amine functional groups. The Boc-protected amine allows for controlled deprotection in multi-step syntheses, making it valuable in the preparation of complex heterocyclic molecules for medicinal chemistry. Also utilized in the production of agrochemicals and bioactive molecules where thiazole rings are structural components.
