2,2-Dipyridyl
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.

Sourcing 2,2-Dipyridyl from Zhangjiagang Clent Chemical - China Import Guide
Before placing an order for 2,2-Dipyridyl with Zhangjiagang Clent Chemical, confirm the supplier's export credentials and request a sample batch with a full Certificate of Analysis. Verify the purity, melting point, and appearance against your specifications, and check that the SDS is complete and current. As the supplier's response metrics are not yet established on the platform, allow extra time for initial communication and specification alignment.
For logistics, confirm whether the supplier ships from Zhangjiagang directly or via Shanghai port, and ask about typical lead times from order confirmation to dispatch. Discuss packaging options, as laboratory-grade material may ship in smaller units (1 kg bottles) while industrial quantities typically move in 25 kg drums. Clarify Incoterms early in negotiations, and confirm whether the supplier handles export customs clearance or if you need to engage a forwarding agent.
Quality assurance for 2,2-Dipyridyl should include verifying the batch identity via CAS number, checking the melting point range (69 to 73°C), and confirming solubility characteristics. For analytical applications, test the reagent blank to ensure it does not introduce interfering absorbance at 522 nm. Establish a clear specification agreement with the supplier covering purity limits, acceptable impurity profiles, and packaging integrity before committing to recurring orders.
