Used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of antiparasitic and antifungal agents. Its aldehyde functional group allows for easy modification in organic reactions, making it valuable in creating biologically active compounds. Commonly employed in the development of benzimidazole-based drugs that target gastrointestinal disorders and infections. Also utilized in coordination chemistry as a ligand precursor for metal complexes with potential catalytic or antimicrobial properties.
