Chemical Properties
white to light yellow crystal
Uses
2-Hydroxypyridine is a bifunctional catalyst for a wide variety of acylation reactions, catalyst for generating β-oxopropyl carbonates from cyclic carbonates and alcohols and in the aminolysis of a polyglutamate. It is used in peptide synthesis.
Uses
Catalyst for generating β-oxopropyl carbonates from cyclic carbonates and alcohols and in the aminolysis of a polyglutamate.
Definition
ChEBI: 2-Hydroxypyridine is a monohydroxypyridine that is pyridine substituted by a hydroxy group at position 2. It has a role as a plant metabolite.
General Description
2-Hydroxypyridine, an enolic tautomer of 2-pyridone, belongs to the class of volatile organic compounds (VOCs).
Safety Profile
Moderately toxic by intraperitoneal and intravenous routes. A combustible liquid. When heated to decomposition it emits toxic vapors of NOx.
Purification Methods
Distil the pyridone under vacuum to remove coloured impurity, then recrystallise from *benzene, CCl4, EtOH or CHCl3/diethyl ether. It can be sublimed under high vacuum. [DePue et al. J Am Chem Soc 107 2131 1985, Beilstein 21/7 V 106.]
