Used primarily as an intermediate in the synthesis of azo dyes and pigments, especially for producing yellow and orange shades in textiles, plastics, and printing inks. It also serves in the manufacture of agrochemicals, including certain herbicides and fungicides, due to its ability to form biologically active compounds. Additionally, it is employed in the production of specialty polymers and rubber chemicals, where it contributes to improved heat and UV stability. Its reactivity makes it valuable in organic synthesis for pharmaceuticals and fine chemicals, particularly in reactions requiring chlorinated aniline derivatives.
