Used in the synthesis of dyes and fluorescent whitening agents due to its aromatic structure and amine functionality. Its methoxy and amine groups enhance electron donation, making it valuable in creating compounds with strong light absorption and emission properties. Commonly employed in the production of optical brighteners for textiles, paper, and detergents. Also serves as an intermediate in the preparation of pharmaceuticals and agrochemicals where naphthalene derivatives are required. Its derivatives can be found in some specialty polymers and photoactive materials.
