Used in organic synthesis as a building block for pharmaceuticals and biologically active compounds. Serves as a key intermediate in the preparation of benzimidazole-based drugs, which exhibit antiparasitic, antiviral, and anticancer properties. Its functional groups enable conjugation in peptide-like structures, making it valuable in medicinal chemistry for designing enzyme inhibitors and receptor ligands. Also employed in the development of fluorescent probes and imaging agents due to the benzimidazole core’s photophysical properties.
