Import Biphenyl-4, 4-Dicarboxylic Acid — Buy in Bulk from Supplier in China

Biphenyl-4,4-dicarboxylic acid from Realychem Co.Ltd is a solid organic compound with the molecular formula C14H10O4, supplied at a minimum purity of 99%. It is soluble in organic solvents, which makes it a dependable intermediate for downstream chemical processes. The white to off-white crystalline powder is stable under standard storage conditions, ensuring consistent performance in synthesis applications where thermal and chemical resistance are required.

The compound is produced to meet stringent industrial standards for aromatic dicarboxylic acids, with typical ash content below 0.1% and heavy metal impurities under 10 ppm. In polymer chemistry, its biphenyl backbone contributes rigidity and thermal stability to resins and polyesters, while its dicarboxylic functionality enables copolymerisation with diols or diamines. Industry standard grades for this class of compound often specify a melting point range of 295 - 300 °C, which aligns with the behaviour of this material in laboratory and pilot-scale reactions.

Manufacturers in coatings, adhesives and pharmaceuticals use this product as a building block for high-performance materials. Buyers typically source it in 25 kg drums for pilot runs or larger bulk containers for continuous production. Confirm packaging, lead time and incoterms with Realychem Co.Ltd, as these are not fixed in the listing. The compound is shipped from Taizhou, Zhejiang, a hub for chemical exports in eastern China.

Realychem Co.Ltd is based in Taizhou, Zhejiang Province, China, an industrial region recognised for its chemical manufacturing and export infrastructure. The company operates as an imported-tier supplier, indicating it sources or produces materials for international markets. Its product portfolio includes specialty organic compounds, with Biphenyl-4,4-dicarboxylic acid listed among its offerings for industrial buyers.

The supplier’s profile shows a harbor trust tier and a response rate of 0.00, which suggests limited engagement through the platform. No verified certifications, production capacity or client references are provided in the available data, so buyers should request documentation such as ISO certificates, COAs and third-party test reports directly from Realychem Co.Ltd before placing orders.
