从China供应商批量进口4-Iodobiphenyl

4-Iodobiphenyl is a halogenated aromatic compound with the CAS number 1591-31-7 and molecular formula C12H9I. Supplied by Wuhan Kemi-Works Chemical Co., Ltd., it appears as a pale-yellow to off-white solid. The material is assay-confirmed at 99.0% minimum purity by HPLC, with a melting point range of 110 - 114°C. Impurities are controlled to a maximum of 2%, with 4,4-iodobiphenyl specifically capped at 1.5% max. Loss on drying is limited to 1% max, ensuring stability for downstream applications.

The compound is a biphenyl derivative where iodine is positioned at the 4-carbon of one phenyl ring, a structure that influences its reactivity in cross-coupling reactions such as Suzuki or Ullmann couplings. Typical for aryl iodides, it offers good leaving-group properties for C-C bond formation. Industry standard grades for such intermediates often target purity above 98% for consistent performance in synthesis, with residual solvent and heavy metal content monitored per pharmacopoeial or agrochemical guidelines.

This intermediate is primarily used in the synthesis of pharmaceuticals, liquid crystals, and organic electronic materials. Buyers in these segments typically require tightly controlled impurity profiles to avoid side reactions. Packaging is supplied in 20 kg fiber drums, a common format for specialty chemicals that balances handling convenience with contamination control. Importers should confirm compatibility with their logistics chain, as fiber drums are robust but may require additional protection for air or sea freight.

Wuhan Kemi-Works Chemical Co., Ltd. operates from Rm. 1503, No. 164, Jianghan North Rd. in Wuhan, Hubei, China. The company is classified as an imported-tier supplier with a harbor trust tier, indicating a baseline level of verification for international trade. Its profile does not disclose response metrics, so buyers should expect to initiate contact directly for technical or commercial inquiries.

The supplier focuses on specialty chemical intermediates, with 4-iodobiphenyl representing a core offering in its portfolio. No additional certifications, production capacity, or client references are provided in the listing, which limits the publicly available information. Buyers are advised to request documentation such as COAs, MSDS, and compliance statements for REACH or other relevant regulations before proceeding with orders.
