Used primarily as an intermediate in the synthesis of azo dyes and pigments, especially for producing yellow and orange shades in textiles, inks, and coatings. It also serves in the manufacture of agrochemicals, including certain herbicides and insecticides, due to its ability to form biologically active molecules. Additionally, it finds use in the production of specialty polymers and rubber chemicals, where it acts as a curing agent or antioxidant precursor. Its reactivity makes it valuable in organic synthesis for pharmaceuticals and fine chemicals.
