Used primarily as an intermediate in the synthesis of hair dyes and pigments due to its ability to form stable azo dyes when diazotized and coupled with other aromatic compounds. It is also employed in the production of specialty polymers and dyes for textiles, where its chlorine and amino groups contribute to improved color fastness and chemical resistance. Additionally, it serves as a building block in the preparation of certain pharmaceuticals and agrochemicals requiring chlorinated aromatic diamines.
