Used as an intermediate in the synthesis of dyes and pigments, particularly azo dyes, due to its ability to undergo diazotization and coupling reactions. It serves in the production of fluorescent whiteners and optical brighteners for textiles and paper. Also employed in the development of certain pharmaceuticals and agrochemicals where naphthalene-based structures are required. Its amino and hydroxyl groups allow for derivatization in organic synthesis, making it useful in research for creating complex aromatic compounds.
