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.

General Description

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

Purification Methods

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