Chemical Structure
Description
4-Bromo-1-(pyridin-4-ylmethyl)pyridin-2(1h)-one (CAS 2090429-68-6) is a high-purity analytical reference standard with the molecular formula C11H9BrN2O and a molecular weight of 265.11 g/mol.
The molecular framework of 4-Bromo-1-(pyridin-4-ylmethyl)pyridin-2(1h)-one (C11H9BrN2O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Bromo-1-(pyridin-4-ylmethyl)pyridin-2(1h)-one 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.
