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.
2-((4-Bromobenzyl)oxy)-1,4-difluorobenzene (CAS 845866-76-4), molecular formula C13H9BrF2O and molecular weight 299.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((4-Bromobenzyl)oxy)-1,4-difluorobenzene (C13H9BrF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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).
CATO manufactures 2-((4-Bromobenzyl)oxy)-1,4-difluorobenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
