Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes. It plays a role in the development of colorants for textiles, inks, and coatings due to its ability to undergo diazotization and coupling reactions. Also employed in the preparation of certain pharmaceuticals where nitro-aromatic scaffolds are required. Its amino and hydroxyl functional groups allow for derivatization in organic synthesis, making it valuable in research and development of fine chemicals.
