Chemical Structure
Description
As a certified reference material (CRM), 2-{[(3-chlorophenyl)methyl]sulfanyl}-6-methyl-3,4-dihydropyrimidin-4-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.
2-{[(3-chlorophenyl)methyl]sulfanyl}-6-methyl-3,4-dihydropyrimidin-4-one (CAS 195002-80-3), molecular formula C12H11ClN2OS and molecular weight 266.75 g/mol, is a CATO reference standard with documented purity and traceability.
2-{[(3-chlorophenyl)methyl]sulfanyl}-6-methyl-3,4-dihydropyrimidin-4-one (C12H11ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
