Description
CATO supplies 5,6,7,8-Tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (CAS 27285-09-2), a certified reference material (molecular formula C10H10N2O2S, MW 222.26 g/mol) for analytical method development and quality control.
The molecular framework of 5,6,7,8-Tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (C10H10N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures 5,6,7,8-Tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione 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.
