3-Hydroxypyridine Usage And Synthesis

Chemical Properties

white to light yellow crystal

Definition

ChEBI: A monohydroxypyridine that is pyridine in which the hydrogen at position 3 has been replaced by a hydroxy group.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 psychoac ive plant.

brand name

Ventavis (Schering).

Purification Methods

Crystallise 3-hydroxypyridine from *C6H6, water or EtOH. [Beilstein 21 III/IV 402, 21/2 V 68.]
