Hydroquinone bis(2-hydroxyethyl) ether (HQEE) (CAS NO : 104-38-1)

Hydroquinone bis(2-hydroxyethyl) ether (CAS 104-38-1), also known as HQEE, serves as a premier symmetrical aromatic diol chain extender specifically engineered for high-performance MDI-based polyurethane elastomers, where its rigid aromatic backbone significantly elevates the glass transition temperature and enhances hard-segment crystallinity compared to aliphatic alternatives. The global specialty chemical market is currently seeing a strategic shift towards HQEE-MDI systems as a viable, high-performance alternative to MOCA-TDI systems, driven by its ability to deliver superior tensile strength, tear resistance, and exceptional dynamic properties with low hysteresis in demanding applications such as industrial wheels, oil-field seals, and heavy-duty mining components. Furthermore, the compound is increasingly valued in the advanced polymer sector as a reactive intermediate for high-durability polyester resins and specialty coatings, providing essential thermal stability and chemical resistance required for next-generation industrial finishes. As a globally established Hydroquinone bis(2-hydroxyethyl) ether (HQEE) supplier with 99% purity, we ensure dependable supply, consistent quality, and complete regulatory documentation, including Hydroquinone bis(2-hydroxyethyl) ether (HQEE) CoA and Hydroquinone bis(2-hydroxyethyl) ether (HQEE) TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with GMP-compliant quality assurance, regulatory documentation, and global supply chain and logistics coordination.
