Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports peptide mimetic design, making it valuable in medicinal chemistry for creating enzyme inhibitors. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of protected functional groups that allow selective deprotection and coupling. Also utilized in research settings for developing novel benzimidazole-based therapeutics with potential antiviral, anticancer, or anti-inflammatory activity.
