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 4-Hydroxy-2-(methylthio)-6-(trifluoromethyl)pyrimidine (CAS 16097-62-4), a certified reference material (molecular formula C6H5F3N2OS, MW 210.18 g/mol) for analytical method development and quality control.
The molecular framework of 4-Hydroxy-2-(methylthio)-6-(trifluoromethyl)pyrimidine (C6H5F3N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-Hydroxy-2-(methylthio)-6-(trifluoromethyl)pyrimidine 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.
