2-Hydroxypyridine Chemical Properties,Usage,Production

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.]
