Description
CATO manufactures 2,3,5,6-Tetrachloro-4-(trifluoromethyl)benzoyl fluoride 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.
2,3,5,6-Tetrachloro-4-(trifluoromethyl)benzoyl fluoride (CAS 117338-22-4), molecular formula C8Cl4F4O and molecular weight 329.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2,3,5,6-Tetrachloro-4-(trifluoromethyl)benzoyl fluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
