Applications
2-Mercaptopyridine N-oxide is used in ratiometric fluorescence imaging of intracellular zinc ions in mammalian cultures. It is used in the radical coupling of benzoyl derivatives of 2-deoxy-D-ribose, with heterocyclic bases to give C-nucleosides. It acts as a ligand and form coordination complexes with palladium chloride. It is a precursor to O-acyl thiohydroxamates. Further, it serves as an antifungal agent. In addition to this, it is used in the preparation of 1-oxa-2-oxo-3-thia-indolizinium chloride by reaction with carbonyl dichloride.

Solubility
Soluble in tris-hydrochloric acid.

Notes
Incompatible with strong oxidizing agents and strong bases.
