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.
CATO supplies 1-(2-Oxo-2-phenylethyl)pyridin-1-ium bromide (CAS 16883-69-5), a certified reference material (molecular formula C13H12NOBr, MW 278.15 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Oxo-2-phenylethyl)pyridin-1-ium bromide (C13H12NOBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1-(2-Oxo-2-phenylethyl)pyridin-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.
