Description
CATO supplies 2,3,5-Trifluoro-4-(trifluoromethyl)pyridine (CAS 675602-93-4), a certified reference material (molecular formula C6HF6N, MW 201.07 g/mol) for analytical method development and quality control.
2,3,5-Trifluoro-4-(trifluoromethyl)pyridine (C6HF6N) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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), 2,3,5-Trifluoro-4-(trifluoromethyl)pyridine 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.
