Description
2-Mercaptopyridine N-oxide is a heterocyclic organosulfur compound with the empirical formula C₅H₅NOS and CAS number 1121-31-9. It has a molar mass of 127,17 g/mol. The pyridine N-oxide core bearing a mercapto substituent makes this reagent of interest in coordination chemistry, ligand design, and selected organic transformations where sulfur–nitrogen heterocycles are required. Researchers in chemical and biochemical laboratories employ it as a specialised building block or additive when exploring metal-binding behaviour or preparing related derivatives. Clear CAS registration and a stated molecular formula support traceable documentation in experimental records. The material is available from manufacturer Carl ROTH within the biochemicals and fine-chemicals range. Storage conditions are specified for the product and should be observed to maintain integrity during handling and inventory.
This article is part of Bases & alkalis, in Acids & bases.

Questions about 2-Mercaptopyridine N-oxide, 50 g
What is this article?
2-Mercaptopyridine N-oxide, 50 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
