2,3-Dihydroxypyridine Usage And Synthesis

Chemical Properties	khaki to grey or brown crystalline powder
Uses	2,3-Dihydroxypyridine(DHP) was used in the synthesis of DHP loaded amberlite XAD-2 via azo coupler. It was used in the synthesis of new macromolecular chelators by loading DHP on cellulose via linkers -NH-CH₂-CH₂-NH-SO₂-C₆H₄-N=N- and -SO₂-C₆H₄-N=N.
Definition	ChEBI: A dihydroxypyridine in which the two hydroxy groups are located at positions 2 and 3.
