Chemical Structure
Description
The molecular framework of 4-Bromo-1-(2-fluorobenzyl)pyridin-2(1h)-one (C12H9BrFNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-Bromo-1-(2-fluorobenzyl)pyridin-2(1h)-one (CAS 2091867-04-6) is a high-purity analytical reference standard with the molecular formula C12H9BrFNO and a molecular weight of 282.11 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
