Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders and inflammatory conditions. It serves as a building block for bioactive molecules due to its ability to form hydrogen bonds and participate in enzyme inhibition. Commonly employed in the preparation of benzimidazole derivatives with antimicrobial, antiviral, and antitumor activities. Also utilized in research for designing kinase inhibitors and receptor antagonists. Its carboxylic acid group allows for easy functionalization, enabling conjugation into larger drug-like structures.
