Used as a dye intermediate in the production of azo dyes for textiles and leather. Due to its aromatic amine structure, it serves as a building block in organic synthesis, particularly in the development of colorants and functional materials. It is also employed in research settings for the synthesis of compounds with potential biological activity and as a model compound in toxicology and carcinogenesis studies, including investigations of cancer mechanisms, liver enzyme changes related to toxin metabolism, and as a standard for analyzing similar chemicals in biochemistry and pharmacology. Related azo compounds are known for their mutagenic and carcinogenic properties, so handling requires caution in laboratory environments.
