Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Mercapto-3-(3-methoxyphenyl)-6,7-dihydrothieno[3,2-d]pyrimidin-4(3H)-on+.
2-Mercapto-3-(3-methoxyphenyl)-6,7-dihydrothieno[3,2-d]pyrimidin-4(3H)-on+ (CAS 1105190-23-5), molecular formula C13H12N2O2S2 and molecular weight 292.38 g/mol, is a CATO reference standard with documented purity and traceability.
2-Mercapto-3-(3-methoxyphenyl)-6,7-dihydrothieno[3,2-d]pyrimidin-4(3H)-on+ (C13H12N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Mercapto-3-(3-methoxyphenyl)-6,7-dihydrothieno[3,2-d]pyrimidin-4(3H)-on+ 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.
