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.
1-Bromo-3-(trifluoromethyl)-5-ethoxybenzene (CAS 1310416-62-6), molecular formula C9H8BrF3O and molecular weight 269.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-3-(trifluoromethyl)-5-ethoxybenzene (C9H8BrF3O) 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 the polarity and ionization state of its functional groups, 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.
As a certified reference material (CRM), 1-Bromo-3-(trifluoromethyl)-5-ethoxybenzene 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.
