Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antiparasitic agents such as benzimidazoles (e.g., albendazole, mebendazole) and antihistamines. It serves as a building block for compounds with biological activity, including drugs targeting protozoal and helminth infections. Its di-amine structure facilitates the formation of fused heterocyclic systems that interact with enzymes and receptors in pathogenic organisms. Also employed in research for developing new benzimidazole derivatives with potential therapeutic effects against infections and inflammation.
