Description
As a certified reference material (CRM), 1-Bromo-2,4,5-trifluoro-3-methylbenzene 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.
1-Bromo-2,4,5-trifluoro-3-methylbenzene (CAS 112822-82-9), molecular formula C7H4BrF3 and molecular weight 225.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/bromine substitution, an aromatic ring system, 1-Bromo-2,4,5-trifluoro-3-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.01 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).
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.
