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.
Application
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.
