2,3-Diaminopyridine Chemical Properties,Usage,Production

Chemical Properties

Brown powder

Uses

2,3-Diaminopyridine was used in the synthesis of 2,3-diaminopyridinium-4-hydroxybenzoate1. It was used as internal standard in analysis of poly(amidoamine)dendrimers having different terminal functionalities by capillary electrophoresis. It was used as reagent in synthesis of imidazopyridines and organometallic complexes.

Application

2,3-diaminopyridine is as intermediates for making a variety of pharmaceutically important compounds, such as it is useful in the production of imidazole pyridine inotropic agents.

General Description

2,3-Diaminopyridine forms the bis-condensed Schiff base with salicylaldehyde. It forms charge transfer complex with tetrachloro-p-benzoquinone and tetracyanoethylene.

Synthesis

2,3-Diaminopyridine has been prepared by reduction of 2-amino-3-nitropyridine with iron and aqueous acidified ethanol, tin and hydrochloric acid.

Purification Methods

It crystallises from *benzene and sublimes in vacuo. [Beilstein 22/11 V 241.]
