Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of naphthol-based azo dyes which are valued for their color fastness and brightness in textile applications. Also employed in the development of fluorescent whiteners for paper and laundry additives. Shows potential in organic electronics as a building block for emissive materials due to its naphthalene core. Additionally, it serves as a derivatizing agent in analytical chemistry to enhance detection of carboxylic acid-containing compounds.
