Chemical Structure

5H-Thiochromeno[2,3-b]pyridin-5-one CAS 5698-68-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 5H-Thiochromeno[2,3-b]pyridin-5-one (CAS 5698-68-0), a certified reference material (molecular formula C12H7NOS, MW 213.26 g/mol) for analytical method development and quality control.

5H-Thiochromeno[2,3-b]pyridin-5-one (C12H7NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
