CATO supplies 2-Mercapto-7-methyl-3-phenyl-5,6,7,8-tetrahydrobenzo-[4,5]thieno[2,3-d]pyrimidin-4(3H)-one (CAS 299919-85-0), a certified reference material (molecular formula C17H16N2OS2, MW 328.45 g/mol) for analytical method development and quality control.
The molecular framework of 2-Mercapto-7-methyl-3-phenyl-5,6,7,8-tetrahydrobenzo-[4,5]thieno[2,3-d]pyrimidin-4(3H)-one (C17H16N2OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-Mercapto-7-methyl-3-phenyl-5,6,7,8-tetrahydrobenzo-[4,5]thieno[2,3-d]pyrimidin-4(3H)-one 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.
