  • Applications

    2-Naphthaleneethanol, 1,2,3,4-tetrahydro- (CAS number: 5441-06-5) is primarily used as an intermediate in the synthesis of fragrance ingredients and aroma compounds, enabling the development of complex aromatic derivatives for perfumery and cosmetics. It may also function as a specialty solvent or co-solvent in formulation and industrial manufacturing processes. As an organic building block, it serves as a precursor in pharmaceutical synthesis and in the production of plastics and polymeric materials. In coatings and inks, or surface-finishing systems, it can appear as an intermediate or processing feedstock. Overall, its exact applications depend on local regulations and formulation limits, and use should comply with safety and chemical-management guidelines.
