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-Benzyl-7-methylquinolin-1-ium bromide (CAS 1139719-95-1), molecular formula C17H16NBr and molecular weight 314.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H16NBr, 1-Benzyl-7-methylquinolin-1-ium bromide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.23 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-Benzyl-7-methylquinolin-1-ium 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.
