Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.07 g/mol gives 2,3,4,5-Tetrafluorobenzotrifluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3,4,5-Tetrafluorobenzotrifluoride (CAS 654-53-5), a certified reference material (molecular formula C7HF7, MW 218.07 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, an aromatic ring system, 2,3,4,5-Tetrafluorobenzotrifluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.07 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).
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), 2,3,4,5-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.
