Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 5-Bromo-2-fluoroanisole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 5-Bromo-2-fluoroanisole (CAS 103291-07-2), a certified reference material (molecular formula C7H6BrFO, MW 205.02 g/mol) for analytical method development and quality control.
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.
As a certified reference material (CRM), 5-Bromo-2-fluoroanisole 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.
