Used as an intermediate in the synthesis of azo dyes and pigments, particularly for producing yellow and orange shades with good lightfastness. Employed in the development of functional dyes for textiles, plastics, and coatings. Also serves as a building block in organic synthesis for pharmaceuticals and agrochemicals due to its aromatic structure and reactive functional groups. Its derivatives may be explored in the design of fluorescent probes or sensors owing to the naphthalene backbone’s inherent photophysical properties.
