2,2'-Bipyridine Chemical Properties,Uses,Production

Chemical Properties

White crystalline powder

Uses

A high-affinity chelator of iron

Uses

As a reagent for the determination of iron.

Uses

2,2'-bipyridine acts as a bidentate chelating ligand which form complexes with transition metal ions and shows antifungal, antibacterial and antiviral activity. It is used for the colorimetric determination of iron as well as oxidation reduction indicators to confirm the presence of ferrous ion in soils. It forms complexes with ruthenium and platinum, exhibit intense luminescence, which may have practical applications. Copper(I) bipyridine complexes involved in the oxidation of alcohols under aerobic conditions.

Definition

ChEBI: A bipyridine in which the two pyridine moieties are linked by a bond between positions C-2 and C-2'.

General Description

2,2′-Bipyridyl, 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.

Biochem/physiol Actions

Metalloprotease inhibitor, high-affinity chelator of iron; may inhibit Fe2+ containing enzymes at 10?8?M.

Safety Profile

Poison by ingestion,subcutaneous, and intraperitoneal routes. Experimentalteratogenic data. Questionable carcinogen withexperimental tumorigenic data. Mutation data reported.When heated to decomposition it emits toxic fumes ofNOx.

Purification Methods

2,2'-Bipyridyl crystallises from hexane, or EtOH, or (after charcoal treatment of a CHCl3 solution) from pet ether. Also, it precipitates from a concentrated solution in EtOH by addition of H2O. Dry it in a vacuum over P2O5. It can be further purified by chromatography on Al2O3 or by sublimation. UV (EtOH): at 280nm (log 4.13). max [Airoldi et al.
