Chemical Structure
Description
As a certified reference material (CRM), 3-Bromo-2-fluorobenzotrifluoride 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.
3-Bromo-2-fluorobenzotrifluoride (CAS 144584-67-8) is a high-purity analytical reference standard with the molecular formula C7H3BrF4 and a molecular weight of 243.00 g/mol.
The molecular framework of 3-Bromo-2-fluorobenzotrifluoride (C7H3BrF4) is characterized by 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
