| | 2,3-Diaminopyridine Usage And Synthesis |
| 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.] |
