  • Applications

    Durene (CAS 95-93-2) is primarily used as an intermediate in the synthesis of specialty aromatic compounds. It serves as a building block for dyes, pigments, and pharmaceutical intermediates, and is used to prepare high-melting, rigid hydrocarbon derivatives for specialty polymers and resins. In coatings, inks, and adhesives research, durene can function as a non-polar, high-boiling hydrocarbon component or additive in formulation studies. The chemical is also used as a high-purity reference material or calibration standard in analytical laboratories for aromatic hydrocarbon analysis. In some process-chemistry contexts, it may be evaluated as a solvent or diluent in niche high-temperature applications, subject to local regulations and formulation limits.
