Used primarily as an intermediate in the synthesis of dyes and pigments, particularly for hair dyes and textile coloring. It plays a key role in producing complex colorants due to its ability to form stable aromatic structures. Additionally, it is employed in the manufacture of certain pharmaceuticals and agrochemicals, where it acts as a building block for more complex molecules. Its applications also extend to research and development in organic chemistry, where it is utilized for studying reaction mechanisms and developing new compounds.
