| 3-Hydroxypyridine Usage And Synthesis |
| Chemical Properties | white to light yellow crystal. Soluble in alcohol and water, slightly soluble in ether and benzene. It becomes a red solution when it encounters ferric chloride, and it is easy to decompose in the air. | | Uses | 3-Hydroxypyridine (cas# 109-00-2) is a compound useful in organic synthesis. | | Preparation | 3-hydroxypyridine was prepared by reacting furfurylamine with H2O2 in the presence of HCl, followed by hydrolysis. The optimal conditions were found as fellows: molar ratio of furfurylamine: HCl : H2O2 = 1 : 5 : 1.1, and H2O2 added dropwisely at 0-5 °C, and then refluxed at 100-105 °C for 0.5 h. | | Definition | ChEBI: 3-Hydroxypyridine is a monohydroxypyridine that is pyridine in which the hydrogen at position 3 has been replaced by a hydroxy group. It has been detected as a thermal degradation product from the smoke of the burning leaves of Salvia divinorum, a Mexican psychoactive plant. | | Brand name | Ventavis (Schering). | | Purification Methods | Crystallise 3-hydroxypyridine from *C6H6, water or EtOH.
