Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 299.11 g/mol gives 1-Benzyloxy-4-bromo-2,5-difluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Benzyloxy-4-bromo-2,5-difluorobenzene (CAS 901238-24-2), a certified reference material (molecular formula C13H9BrF2O, MW 299.11 g/mol) for analytical method development and quality control.
The molecular framework of 1-Benzyloxy-4-bromo-2,5-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Benzyloxy-4-bromo-2,5-difluorobenzene 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.
