294653-45-5 2-Mercapto-5-phenyl-3H-thieno[2,3-d]pyrimidin-4-one MFCD03656342 CAS 294653-45-5

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 294653-45-5 2-Mercapto-5-phenyl-3H-thieno[2,3-d]pyrimidin-4-one MFCD03656342 (CAS 294653-45-5), a certified reference material (molecular formula C12H8N2OS2, MW 260.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H8N2OS2, 294653-45-5 2-Mercapto-5-phenyl-3H-thieno[2,3-d]pyrimidin-4-one MFCD03656342 contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
