Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its amine functionality and chlorinated aromatic structure. It also serves in the manufacture of certain pharmaceuticals and agrochemicals where chlorinated phenolic compounds are required. Its reactivity allows for easy modification in multi-step organic syntheses, including the formation of heterocyclic compounds and antimicrobial agents. Handling requires caution due to potential toxicity and irritant properties.
