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 2-Bromo-1-(2,2-diethoxyethoxy)-4-fluorobenzene (CAS 253429-18-4), a certified reference material (molecular formula C12H16BrFO3, MW 307.16 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-1-(2,2-diethoxyethoxy)-4-fluorobenzene (C12H16BrFO3) is characterized by a carboxylic acid group, 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).
As a certified reference material (CRM), 2-Bromo-1-(2,2-diethoxyethoxy)-4-fluorobenzene 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.
