Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antiparasitic and antiviral agents. Its structure supports the formation of biologically active benzimidazole derivatives, which are known for their interaction with cellular enzymes and receptors. Commonly employed in research settings to design compounds with potential therapeutic effects, including treatments for gastrointestinal disorders and infectious diseases. Also utilized in the preparation of fluorescent dyes and sensors due to its favorable photophysical properties.
