从China供应商批量进口5-Amino-2,4,6-Triiodisophthaloyl Acid Dichlorid

5-Amino-2,4,6-triiodisophthaloyl acid dichloride is the diacid chloride derivative of 5-amino-2,4,6-triiodoisophthalic acid, a reactive intermediate distinguished by its two acyl chloride functional groups that enable direct amidation without additional carboxylic acid activation. With molecular weight 395.25 g/mol and purity exceeding 98% according to Shouguang Kuibao Chemical Technology Co., Ltd's specification, this white crystalline powder serves as a more reactive alternative to the free acid in convergent synthesis of nonionic X-ray contrast agents. The compound's reactivity profile makes it particularly suited for coupling with polyhydroxylated amines under controlled conditions.

The acid chloride groups exhibit characteristic reactivity with nucleophiles, requiring handling under anhydrous conditions to prevent hydrolysis back to the parent diacid. Shouguang Kuibao Chemical Technology Co., Ltd supplies this material from Shouguang, Shandong Province, within the Bohai Chemical Industrial Park, a region with established fine chemical manufacturing infrastructure. The white crystalline appearance indicates proper handling and storage; discoloration to yellow or brown suggests decomposition or inadequate moisture exclusion during production or storage.

Primary applications include pharmaceutical manufacturing of iodinated contrast media, particularly where direct amidation routes reduce overall step count and improve process economics. The compound also finds use in research laboratories developing novel imaging agents and in specialty chemical synthesis where activated carboxylic acid derivatives are required. Buyers should confirm with Shouguang Kuibao Chemical Technology Co., Ltd the specific batch size availability, lead time from order confirmation, and whether technical support for handling and reaction optimization is provided, as the listing does not specify these operational details.

Shouguang Kuibao Chemical Technology Co., Ltd is located at No.8, Bohai Road, Bohai Chemical Industrial Park, Shouguang 262714, Shandong Province, China. The supplier holds an imported tier designation and harbor trust tier on the platform, though their response rate is recorded at 0.00% with zero hours average response time, indicating no active quotation engagement through this particular channel. The company's positioning within a dedicated chemical industrial park suggests access to shared infrastructure for chemical processing, waste management, and environmental compliance typical of such zoned developments in China.

The available profile does not disclose founding date, employee numbers, annual production capacity, revenue figures, specific quality certifications, or named clientele. No GMP compliance, ISO registration, or regulatory filing information appears in the source data. Buyers must independently verify Shouguang Kuibao Chemical Technology Co., Ltd's manufacturing scope license, environmental compliance records, and whether their facilities are subject to or have passed audits by pharmaceutical customers or regulatory authorities. The absence of response history means direct outreach, potentially supplemented by site visit to their Shouguang address, is advisable before committing to supply agreements.
