Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anthelmintic and antiparasitic agents. It plays a key role in developing drugs that target gastrointestinal parasites due to its ability to bind to biological receptors involved in nerve transmission in parasites. Also utilized in research for developing new benzimidazole-derived compounds with potential antimicrobial and antiviral activities. Its hydrochloride salt form improves solubility and stability, making it suitable for formulation in drug development processes.
