Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,5-Difluoro-2-(trifluoromethyl)benzaldehyde (CAS 134099-22-2), molecular formula C8H3F5O and molecular weight 210.10 g/mol, is a CATO reference standard with documented purity and traceability.
4,5-Difluoro-2-(trifluoromethyl)benzaldehyde (C8H3F5O) contains a hydroxyl group, an ether linkage, fluorine 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 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).
As a certified reference material (CRM), 4,5-Difluoro-2-(trifluoromethyl)benzaldehyde 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.
