2-Pyridinol-1-oxide Chemical Properties,Usage,Production

Chemical Properties

Weight 20% solution in water

Uses

2-Pyridinol 1-oxide can be used:

  • To fabricate gold electrodes for the electrochemical determination of europium using cyclic voltammetry.
  • To prepare polymeric nickel (II) complex of 2-hydroxypyridine-N-oxide.
  • In the synthesis of 1-methoxypyrid-4-one in the presence of sodium methoxide and methyl toluene-9-sulphonate.

Definition

Bactericidal agent related to aspergillic acid, made from pyridine-N-oxide.

General Description

2-Pyridinol 1-oxide (HOPO) is a peptide coupling agent used as a subsititue for HOBt. It can form stable chelate complexes with transition metal ions.
