2-Hydroxy-5-pyridinecarboxylic acid Usage And Synthesis
Chemical Properties Off-white powder
Uses 6-Hydroxynicotinic acid is used as building block in chemical synthesis. Product Data Sheet
Uses Nicotinic Acid derivative, found in fruit hypanthium.
Definition ChEBI: A monohydroxypyridine that is the 6-hydroxy derivative of nicotinic acid.
Purification Methods It crystallises from water with m 303.4-303.7o(dec), or with m 325o(dec) from aqueous EtOH. The methyl ester crystallises from Me2CO with m 166o and pK2 0 9.92. [Albert J Chem Soc 1020 1960, Beilstein 22 III/IV 2147, 22/6 V 119.]
