Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of triarylmethane dyes which are valued for their intense colors. It also serves in the manufacture of antioxidants and rubber chemicals, contributing to the stabilization of polymers and elastomers against thermal and oxidative degradation. Additionally, it finds use in the development of certain pharmaceuticals and agrochemicals where substituted anilines are required as building blocks. Due to its reactivity, it is also employed in organic research for constructing complex aromatic amines.
