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.]
