Chemical Structure
Description
As a certified reference material (CRM), 3,4,5-Trifluorobenzoyl chloride 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.
3,4,5-Trifluorobenzoyl chloride (CAS 17787-26-7), molecular formula C7H2ClF3O and molecular weight 194.54 g/mol, is a CATO reference standard with documented purity and traceability.
3,4,5-Trifluorobenzoyl chloride (C7H2ClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
