Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-(4-fluorophenyl)thieno[3,2-d]pyrimidine-4-thiol (CAS 757221-68-4), a certified reference material (molecular formula C12H7FN2S2, MW 262.33 g/mol) for analytical method development and quality control.
6-(4-fluorophenyl)thieno[3,2-d]pyrimidine-4-thiol (C12H7FN2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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.
As a certified reference material (CRM), 6-(4-fluorophenyl)thieno[3,2-d]pyrimidine-4-thiol 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.
