2-Mercaptopyridine | CAS 73018-10-7

A sulfur nucleophile with its thiol/thione site adjacent to the pyridine nitrogen, used in reported pyridyl thioether research. Structural form and sulfur-related impurity controls are more informative than a generic mercaptan description.

CAS73018-10-7
Molecular formulaC5H5NS

Product overview

The sulfur-bearing carbon is directly next to the pyridine nitrogen, creating a compact nitrogen/sulfur heteroaromatic reagent. 2-Mercaptopyridine can be represented through a thiol–thione tautomeric system, so structural comparison is useful when suppliers use different names. Its oxygen-free formula distinguishes it from pyrithione, an oxygen-containing pyridine derivative. In thioether synthesis, the sulfur site supplies the nucleophilic component. Qualification should confirm the C2 connection and the parent reagent before comparing chromatographic purity. Where oxidation-related sulfur components affect the intended reaction, define those compounds and their limits explicitly, together with any water requirement needed for the selected coupling system.

Application context

Published iron-catalyzed coupling research includes pyridine-containing thiols in the formation of carbon–sulfur bonds from alkyl halide partners. For 2-mercaptopyridine, this provides a research context for constructing thioethers containing the 2-pyridyl sulfur fragment.

A useful enquiry identifies the electrophile class and asks for a representative chromatographic profile of the sulfur reagent. The method should distinguish the requested parent from relevant sulfur-derived components. Chemical identity, any functional-group assay and the main chromatographic result should be reviewed together when comparing material for coupling development.

Chemistry and synthetic role

The sulfur function occupies pyridine C2. Thiol and thione representations redistribute the proton and bonding without adding the oxygen present in pyrithione.

Quality review

Confirm the C2 sulfur structure

Distinguish other mercaptopyridine positions and oxygenated pyridine derivatives.

Review sulfur-derived components

Set chromatographic limits for oxidation-related or other sulfur species relevant to the reaction.

Define functional versus chromatographic assay

If a sulfur-functional assay is required, report it separately from chromatographic area purity.

Preparing a specification

Specify 2-mercaptopyridine CAS 73018-10-7 with a matching structural representation, chromatographic profile and any sulfur-functional assay. Add water and relevant sulfur-derived impurity criteria.

Packaging and storage

Packaging, closure and net weight are agreed for the selected grade, order quantity and destination. Confirm storage and transport requirements against the actual supplier SDS.

Documentation

Request a batch COA, specification, identity data and SDS. Confirm the availability of the analytical methods and any application-specific impurity results with the proposed supplier.

Procurement questions

Is this pyrithione?

No. This material has formula C5H5NS and contains no oxygen.

Why may a thione name appear?

The compound belongs to a thiol–thione tautomeric system; compare the structure and identifier.

Which group supplies the thioether sulfur?

The sulfur function attached at pyridine C2 participates as the sulfur nucleophile.
