CATO supplies 2-Mercapto-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrido[2,3-d]pyrimidin-4-ol hydrate (CAS 1171779-93-3), a certified reference material (molecular formula C12H6F3N3OS2H2O, MW 347.33 g/mol) for analytical method development and quality control.
2-Mercapto-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrido[2,3-d]pyrimidin-4-ol hydrate (C12H6F3N3OS2H2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
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-7-(thiophen-2-yl)-5-(trifluoromethyl)pyrido[2,3-d]pyrimidin-4-ol hydrate 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.
