2,2'-DIPYRIDYLAMINE Usage And Synthesis

Description

2,2′-Dipyridylamine is an organic compound with the formula (C5H4N)2NH. It consists of a pair of 2-pyridyl groups (C5H4N) linked to a secondary amine. The compound forms a range of coordination complexes.Its conjugate base, 2,2′-dipyridylamide, forms extended metal atom chains.

Formation

2,2′-Dipyridylamine can be formed by heating pyridine with sodium amide. Alternatively, 2-aminopyridine can be heated with 2-chloropyridine over barium oxide.

Chemical Properties

White solid

Uses

A metal-complexing agent; an effective iron chelating agent to help protect against UVB radiation. An impurity of Chlorpheniramine Maleate (C424300).

Uses

2,2′-Dipyridylamine (bipyam) can be used:

  • As a bidentate N-donor ligand in the synthesis of various metal complexes.
  • To synthesize Pd-polyoxovanadates, heterogeneous catalyst for the oxidation of benzylic hydrocarbons.

General Description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Purification Methods

Crystallise the amine from *benzene or toluene [Blakley & De Armond J Am Chem Soc 109 4895 1987]. The amine is also recrystallised from Me2CO (m 95.1o) or distilled in a vacuum. [Beilstein 22 I 630, 22 II 331, 22 III/IV 3961.]
