Used primarily as an intermediate in the synthesis of dyes, pigments, and agricultural chemicals. It plays a key role in the production of azo dyes due to its ability to undergo diazotization and coupling reactions. Also serves as a building block in the manufacture of certain herbicides and insecticides. Its chlorinated structure makes it suitable for further substitution reactions in organic synthesis, particularly in pharmaceutical development. Limited use in polymer modification and specialty chemicals due to its reactivity and stability under industrial conditions.
