从China供应商批发进口2,2-Dipyridyl — FOB条款

2,2-Dipyridyl, also known as 2,2'-bipyridine, is a heterocyclic aromatic compound with the molecular formula C₁₀H₈N₂ and CAS number 366-18-7. Supplied by Zhangjiagang Clent Chemical Co., Ltd from Jiangsu province, China, this bidentate chelating agent is used extensively in analytical chemistry, particularly for the colorimetric determination of iron(II) ions. The compound forms a distinctive red-purple complex with ferrous ions, a reaction that underpins its role as a standard reagent in environmental and industrial water analysis.

The material is available in laboratory and industrial grades, with typical purity levels in the fine chemical trade ranging from 97% to 99.5%. As a solid at room temperature, 2,2-Dipyridyl is commonly supplied as a white to off-white crystalline powder with a melting point around 69 to 73°C. It is soluble in ethanol, diethyl ether, and dilute acids, and slightly soluble in water, which makes it compatible with standard titration and spectrophotometric workflows.

Buyers of 2,2-Dipyridyl include pharmaceutical manufacturers requiring it as a ligand for organometallic catalyst synthesis, research institutions conducting trace metal analysis, and specialty chemical distributors serving both sectors. Zhangjiagang Clent Chemical is based in Jiangsu, a region with a strong fine chemicals export base. Importers should request a Certificate of Analysis with each batch and confirm MOQ, pricing tiers, and Incoterms directly with the supplier, as these details are not specified in the listing.
