Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-5-fluoro-1-iodo-3-methylbenzene.
2-Bromo-5-fluoro-1-iodo-3-methylbenzene (CAS 1805591-75-6), molecular formula C7H5BrFI and molecular weight 314.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-5-fluoro-1-iodo-3-methylbenzene (C7H5BrFI) is characterized by fluorine/bromine/iodine 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 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.
As a certified reference material (CRM), 2-Bromo-5-fluoro-1-iodo-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.
