Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 151.19 g/mol gives Thieno[3,2-c]pyridin-7(6H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Thieno[3,2-c]pyridin-7(6H)-one (CAS 37831-43-9), a certified reference material (molecular formula C7H5NOS, MW 151.19 g/mol) for analytical method development and quality control.
The molecular framework of Thieno[3,2-c]pyridin-7(6H)-one (C7H5NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
