Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anthelmintic drugs like flubendazole and mebendazole. It serves as a building block for constructing benzimidazole-based compounds, which exhibit broad-spectrum antiparasitic activity. Its ester and amino functional groups allow for selective chemical modifications, enabling efficient route optimization in drug manufacturing. Also employed in agrochemical research for developing crop protection agents due to its halogenated aromatic structure, which enhances bioactivity and stability.
