2-Pyridinethiol 1-oxide Chemical Properties,Uses,Production

Chemical Properties

off-white powder

Uses

Precursor to O-acyl thiohydroxamates. Ligates to metals to form biologically active complexes.

Uses

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.

Definition

ChEBI: Pyrithione is a pyridinethione that is pyridine-2(1H)-thione in which the hydrogen attached to the nitrogen is replaced by a hydroxy group. It is a Zn(2+) ionophore; the zinc salt is used as an antifungal and antibacterial agent. It has a role as an ionophore. It is a pyridinethione and a monohydroxypyridine. It is a tautomer of a pyridine-2-thiol N-oxide.

General Description

2-Mercaptopyridine N-oxide forms complexes on reaction with palladium chloride. It inhibits NADH-fumarate reductase purified from Trypanosoma cruzi. It is precursor to O-acyl thiohydroxamates. It ligates to metals to form biologically active complexes.
