  • Applications

    1-Ethoxynaphthalene is primarily used as an organic synthesis intermediate and as a non-polar aromatic solvent in industrial formulations. It serves as a precursor in the manufacture of dyes and pigments, enabling further derivatization of the naphthalene ring. In perfumery and cosmetics it can function as a fragrance ingredient or fragrance intermediate. In coatings and inks it is used as a processing solvent or component of resin systems to adjust solvency and formulation properties. In polymer science it can act as a building block for specialty polymers or as a reactive intermediate in polymer modification. Its use is typically governed by formulation requirements and local regulations.
