Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-1-(4-bromo-2-fluoro-6-methylphenyl)ethanone 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.
2-Bromo-1-(4-bromo-2-fluoro-6-methylphenyl)ethanone (CAS 1934465-25-4), molecular formula C9H7Br2FO and molecular weight 309.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-1-(4-bromo-2-fluoro-6-methylphenyl)ethanone (C9H7Br2FO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 309.96 g/mol, it falls into the moderately-high-molecular-weight range. 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.
