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.
1,2-Difluoro-3-iodo-5-methylbenzene (CAS 886038-03-5) is a high-purity analytical reference standard with the molecular formula C7H5F2I and a molecular weight of 254.02 g/mol.
The molecular framework of 1,2-Difluoro-3-iodo-5-methylbenzene (C7H5F2I) is characterized by fluorine/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).
As a certified reference material (CRM), 1,2-Difluoro-3-iodo-5-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.
