Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiparasitic and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building bioactive molecules. Commonly employed in cross-coupling reactions to introduce aryl or heteroaryl groups, facilitating the creation of complex benzimidazole derivatives with potential therapeutic activity. Also utilized in research settings for designing enzyme inhibitors and receptor ligands due to the benzimidazole core’s affinity for biological targets.
