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 3,6-diethyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 744242-07-7), a certified reference material (molecular formula C10H18N2OS2, MW 246.39 g/mol) for analytical method development and quality control.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3,6-diethyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 3,6-diethyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
