Used as an intermediate in the synthesis of dyes and pigments, particularly for producing azo dyes that exhibit bright shades and good lightfastness. It plays a role in the manufacture of specialty chemicals, including optical brighteners for textiles and paper. Also utilized in the development of certain pharmaceuticals and agrochemicals due to its amine functionality and aromatic structure, which support molecular diversification in drug design. Its methoxy-naphthalene core is valuable in creating fluorescent compounds for sensors and imaging agents.
