2-Hydroxy-5-pyridinecarboxylic acid Usage And Synthesis
  • Chemical PropertiesOff-white powder
  • Uses6-Hydroxynicotinic acid is used as building block in chemical synthesis. 
  • UsesNicotinic Acid derivative, found in fruit hypanthium.
  • DefinitionChEBI: A monohydroxypyridine that is the 6-hydroxy derivative of nicotinic acid.
  • Purification MethodsIt 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.]
