Biphenyl-4,4-dicarboxylic acid
Biphenyl-4,4-dicarboxylic acid is an organic compound with the CAS number 787-70-2, supplied by Realychem Co.Ltd in 25 kg drums for wholesale export. This white to off-white crystalline powder is a key intermediate in the synthesis of liquid crystal polymers, polyesters, and pharmaceuticals, where its rigid biphenyl structure imparts thermal stability and mechanical strength to the final product.
The material is typically produced via oxidation of 4,4-dimethylbiphenyl or through stoichiometric routes, yielding a product with purity levels exceeding 98% as standard for industrial use. It is soluble in polar organic solvents like DMSO and DMF under heated conditions, while remaining sparingly soluble in water and non-polar solvents. The compound’s high melting point, often above 300°C for standard grades, makes it suitable for high-temperature polymer processing.
Industrial buyers in the chemical, textile, and pharmaceutical sectors source this acid for applications such as high-performance plastics, fire-resistant fibers, and active pharmaceutical ingredients. Bulk shipments from Taizhou, Zhejiang, are typically offered under FOB or CIF terms, with packaging designed to prevent moisture absorption. Buyers should confirm exact purity, particle size distribution, and residual solvent content with the supplier before ordering.

Sourcing Biphenyl-4,4-dicarboxylic acid from Realychem Co.Ltd - China Import Guide
Before placing an order with Realychem Co.Ltd, verify the exact purity, particle size, and residual solvent content of the Biphenyl-4,4-dicarboxylic acid. Request a certificate of analysis and, if applicable, a sample for in-house testing to confirm suitability for your specific application.

Lead times can vary based on production schedules and shipping availability, so request a firm delivery timeline. Packaging should be checked for compliance with international shipping regulations for chemicals.
Quality checks should include visual inspection for color and particle consistency, as well as laboratory testing for purity and moisture content.
