Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of benzimidazole-based drugs which exhibit antiparasitic, antiviral, and anticancer activities. It serves as a building block in the development of histamine H2-receptor antagonists and proton pump inhibitors for treating gastrointestinal disorders. Also employed in agrochemicals to enhance the efficacy of pesticides and in the preparation of corrosion inhibitors for metal protection. Its amide group enables easy functionalization, making it valuable in medicinal chemistry and drug design.
