Verwenden
4-Hydroxypyridine was used in the synthesis of (Ag

3MoO
4)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ChEBI: A monohydroxypyridine that is pyridine in which the hydrogen at position 4 has been replaced by a hydroxy group.
l?uterung methode
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.]
