  • Applications

    1,2-Dimethylnaphthalene (CAS 28804-88-8) is primarily used as a chemical intermediate in the synthesis of higher-value aromatics and specialty compounds. In industrial manufacturing, it can function as a non-polar solvent or a reaction diluent for various processes, and as a building block supplying feedstock for dyes, pigments, and other PAH-derived intermediates. It is also considered a precursor in the development of polymers and plastics formulations, contributing as a hydrocarbon feedstock for specialty polymers. Additionally, it may be employed as a processing aid or component in coatings and inks formulations, and is evaluated for research and development use as a high-boiling hydrocarbon solvent. Its handling and applications are typically subject to local regulations and formulation limits.
