Chemical Structure
Description
2,3,5,6-Tetrafluorobenzotrifluoride (CAS 651-80-9), molecular formula C7HF7 and molecular weight 218.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3,5,6-Tetrafluorobenzotrifluoride (C7HF7) is characterized by fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,3,5,6-Tetrafluorobenzotrifluoride 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.
