Description

Compared with other compounds in its class, the molecular weight of 188.25 g/mol gives thieno[3,2-d]pyrimidine-7-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies thieno[3,2-d]pyrimidine-7-carboxylic acid (CAS 1211596-20-1), a certified reference material (molecular formula C7H12N2O2S, MW 188.25 g/mol) for analytical method development and quality control.

thieno[3,2-d]pyrimidine-7-carboxylic acid (C7H12N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).

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

As a certified reference material (CRM), thieno[3,2-d]pyrimidine-7-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
