Description

Dimethyl-2,6-naphthalenedicarboxylate (CAS: 840-65-3) is a high-purity organic compound with the molecular formula C₁₄H₁₂O₄. This white crystalline solid is a dimethyl ester derivative of 2,6-naphthalenedicarboxylic acid, widely utilized as a key intermediate in polymer synthesis and specialty chemical manufacturing. Its rigid naphthalene backbone and ester functional groups make it particularly valuable for producing high-performance polymers such as PEN (polyethylene naphthalate), which exhibits superior thermal stability, mechanical strength, and barrier properties compared to PET. With a melting point of approximately 190-194°C, this compound demonstrates excellent thermal stability for high-temperature applications. Our product is rigorously tested to ensure ≥98% purity (GC) and is supplied with comprehensive analytical documentation including HPLC chromatograms and NMR spectra. Proper storage in a cool, dry place away from strong oxidizers is recommended to maintain product integrity.
