4-Chloro-5-(2,3-dichlorophenoxy)-2-nitroaniline

It serves as a precursor in the, reduction-cyclization process, in which the nitro group is reduced to an amine and subsequently closed into a benzimidazole ring, leading to the formation of 6-chloro-5-(2,3-dichlorophenoxy)-1H-benzimidazole-2-thiol, which is methylated to yield Triclabendazole. 4-Chloro-5-(2,3-dichlorophenoxy)-2-nitroaniline is a critical intermediate in the industrial synthesis of the anthelmintic drug Triclabendazole.
