Description : Ortho-xylene (CAS No. 95-47-6) serves as a fundamental aromatic building block, with approximately 90% of global production dedicated to the catalytic oxidation of its methyl groups to produce phthalic anhydride, a critical precursor for phthalate plasticisers and alkyd resins. The market is currently undergoing a structural shift driven by the rising demand for high-performance unsaturated polyester resins (UPR) in the automotive and renewable energy sectors, where the isomer's unique ortho-substituted structure facilitates the synthesis of materials with superior thermal stability and tensile strength. Furthermore, the global supply chain is increasingly influenced by geopolitical tensions and feedstock volatility in the aromatics complex, necessitating a strategic focus on integrated refinery-to-petrochemical operations to mitigate the impact of fluctuating naphtha costs on downstream speciality chemical derivatives. As globally established O-Xylene (Ortho-Xylene) supplier with high purity %, we ensure dependable supply, consistent quality, and complete regulatory documentation, including O-Xylene (Ortho-Xylene) CoA and O-Xylene (Ortho-Xylene) 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.
