Used as an intermediate in the synthesis of dyes and pigments, particularly for producing azo dyes that exhibit good light and thermal stability. It is also employed in the preparation of organic semiconductors and photoconductive materials used in electrophotography. Additionally, it serves as a building block in the development of pharmaceuticals and agrochemicals due to its aromatic amine functionality, which can undergo various coupling and substitution reactions. Its naphthyl-aniline structure makes it useful in creating ligands for metal complexes in catalysis.
