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 (5-Bromo-2,3-difluoro-4-methylphenyl)methanol (CAS 2484889-29-2), a certified reference material (molecular formula C8H7BrF2O, MW 237.04 g/mol) for analytical method development and quality control.
The molecular framework of (5-Bromo-2,3-difluoro-4-methylphenyl)methanol (C8H7BrF2O) 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), (5-Bromo-2,3-difluoro-4-methylphenyl)methanol 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.
