Used as an intermediate in the synthesis of azo dyes and pigments, particularly for high-performance colorants in inks, coatings, and textiles. Its structure allows for diazotization and coupling reactions, enabling the production of complex dye molecules with enhanced light and wash fastness. Also employed in the preparation of specialty polymers and agrochemicals where aromatic diamines contribute to cross-linking or act as building blocks for heterocyclic systems. Due to the presence of both amine groups and chloro substituent, it offers selective reactivity useful in multi-step organic synthesis.
