China and Germany are the leading exporters of cis-1,2,3,6-Tetrahydrophthalic anhydride (CAS 935-79-5), collectively accounting for over 60% of global export value in 2023–2024, while the United States, South Korea, and India represent the largest importing markets. Import volumes in Asia-Pacific have risen steadily since 2022, coinciding with moderate upward pressure on cis-1,2,3,6-Tetrahydrophthalic anhydride prices amid tightening supply from key European producers.
cis-1,2,3,6-Tetrahydrophthalic anhydride is a white to off-white crystalline solid at room temperature, with a mild characteristic odor and a melting point of approximately 105–108 °C. It is a cyclic organic anhydride derived from partial hydrogenation of phthalic anhydride and is classified as a saturated alicyclic anhydride and key chemical intermediate. Its primary industrial use is as a reactive comonomer and curing agent in unsaturated polyester resins, epoxy resin systems, and alkyd coatings. It is also employed in the synthesis of plasticizers, lubricant additives, and specialty polymers for applications in composites, electrical encapsulants, and high-performance coatings.
