Used primarily as an intermediate in the synthesis of azo dyes and pigments, especially for producing yellow and orange shades used in textile, printing, and ink industries. It also serves in the manufacture of certain agricultural chemicals, including 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 acts as a curing agent or antioxidant. Its reactivity makes it valuable in pharmaceutical synthesis for building complex molecules requiring chlorinated aniline derivatives.
