Chemical Structure
Description
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.
1-{[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}pyridinium bromide (CAS 648427-34-3), molecular formula C12H9ClF3N2Br and molecular weight 353.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H9ClF3N2Br, 1-{[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}pyridinium bromide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 353.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1-{[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}pyridinium bromide 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.
