  • Applications

    1,7-Dimethylnaphthalene (CAS 575-37-1) is primarily used as a chemical intermediate in organic synthesis, supporting the production of aromatic compounds, dyes and specialty polymers. It may act as a non-polar solvent or processing aid in certain industrial formulations, including coatings and inks. It can serve as a precursor in fragrance chemistry and related aroma compound synthesis. The material is also encountered as a processing component in cleaning formulations and other solvent systems. In research and development, it is used as a model compound for aromatic hydrocarbon chemistry and as a starting point for exploring transformations of alkylated naphthalenes.
