Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Ethyl-2-(propylthio)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 338401-67-5) is a high-purity analytical reference standard with the molecular formula C11H14N2OS2 and a molecular weight of 254.37 g/mol.
3-Ethyl-2-(propylthio)thieno[3,2-d]pyrimidin-4(3H)-one (C11H14N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), 3-Ethyl-2-(propylthio)thieno[3,2-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.
