Description
CATO manufactures 4-Bromo-2,3,5,6-tetrafluorotoluene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-Bromo-2,3,5,6-tetrafluorotoluene (CAS 33564-68-0), molecular formula C7H3BrF4 and molecular weight 243.00 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2,3,5,6-tetrafluorotoluene (C7H3BrF4) is characterized by fluorine/bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
