| Hazard Information | Back Directory | [Chemical Properties]
Beige crystalline powder | [Uses]
4-Hydroxypyridine was used in the synthesis of (Ag3MoO3F3) (Ag3MoO4)Cl by hydro(solvato)thermal methods. It was used as model compound to study the natural photodegradation of representative aquatic environmental contaminants. | [Definition]
ChEBI: A monohydroxypyridine that is pyridine in which the hydrogen at position 4 has been replaced by a hydroxy group. | [Purification Methods]
Crystallise 4-pyridone from H2O or wet CHCl3 as the monohydrate. It loses H2O on drying in vacuo over H2SO4. Store it over KOH because it is hygroscopic.[Beilstein 21 III/IV 446, 21/7 V 152.] |
