Used as a key intermediate in the synthesis of high-performance pigments and dyes, particularly in the production of azo and anthraquinone dye classes. It plays an important role in the manufacturing of specialty polymers and aramid fibers due to its aromatic amine structure, which contributes to thermal and chemical resistance. Also employed in the development of photographic chemicals and certain electroactive materials for advanced electronic applications. Its reactivity allows for functionalization in pharmaceutical intermediates and agrochemicals, where chlorinated aromatic diamines enhance biological activity.
