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.
112290-03-6 2-Chloro-4,5-difluorobenzotrifluoride 8928AC C7H2ClF5 (CAS 112290-03-6), molecular formula C7H2ClF5 and molecular weight 216.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 112290-03-6 2-Chloro-4,5-difluorobenzotrifluoride 8928AC C7H2ClF5 (C7H2ClF5) is characterized by fluorine/chlorine 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), 112290-03-6 2-Chloro-4,5-difluorobenzotrifluoride 8928AC C7H2ClF5 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.
