2-Mercaptopyridine N-oxide sodium salt, 40% aq. soln.

Description

CAS: 3811-73-2 | C5H4NNaOS | 149.143 g/mol

2-Mercaptopyridine N-oxide sodium salt is one of the active components in paint, sealants, shampoo, adhesive and aerosol due to its anti-microbial activity. In biochemistry studies, it is utilized to transport zinc into cells. Further, it is used to form bidentate oxothiolane chelates with transition metals. It acts as a stabilizer and viscosity building provider in weak basic or neutral medium.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
