2,2'-Dipyridyl 366-18-7 Usage

2,2'-Dipyridyl is a reagent used for the determination of iron which is White to light red crystalline powder. Soluble in ethanol, ether, benzene, chloroform and petroleum ether, 1 part of this product is about 200 parts of water. It acts as a bidentate chelating ligand which form complexes with transition metal ions and shows antifungal, antibacterial and antiviral activity. It is a symmetrical bipyridine commonly used as a neutral ligand for complexation with metal ions. The molecule is planar with trans-conformation and crystallizes in the monoclinic crystal system.

Definition

ChEBI: 2,2'-bipyridine is a bipyridine in which the two pyridine moieties are linked by a bond between positions C-2 and C-2'. It has a role as a ferroptosis inhibitor and a chelator.

High throughput flow injection /MZ technique for indirect assay of hydrosulfurnyl group in Tiopronin drugs and biological samples using 2,2`-dipyridyl as a selection OAR

Hashim J. Abdullah , Bushra B. Qassim

International Journal of Mechanical Engineering

This method included a reducing reaction between Tiopronin with Fe (III) to produce Fe (II) and then the Fe (II) react with 2,2`-dipyridyl to produce a Pink-red color complex which has maximum absorbance at the wave length 522nm. FIA/MZ was cheap, economical, accurate and precise which the detection limit was 4.0670 µg.mL-1 and RSD% percent about 0.7925% and the recovery is 101.93.
