Used primarily as an intermediate in the synthesis of azo dyes and pigments, particularly for textile and printing inks. It plays a key role in the production of disperse dyes due to its ability to form stable colorants with good fastness properties. Also employed in the manufacture of certain pharmaceuticals and agrochemicals where substituted anilines are required for building active molecules. Its reactivity and solubility profile make it suitable for coupling reactions in dye manufacturing processes.
