Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its amino and ester functional groups. Its naphthalene backbone provides a rigid, aromatic structure that enhances color fastness and thermal stability in dye applications. Also employed in the preparation of fluorescent probes and optical brighteners for textiles and paper. Additionally, it serves as a building block in organic synthesis for pharmaceuticals and agrochemicals where naphthylamine derivatives are required.
