Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(3,5-Ditrifluoromethylphenyl)-5-oxovaleric acid.
5-(3,5-Ditrifluoromethylphenyl)-5-oxovaleric acid (CAS 898788-07-3), molecular formula C13H10F6O3 and molecular weight 328.21 g/mol, is a CATO reference standard with documented purity and traceability.
5-(3,5-Ditrifluoromethylphenyl)-5-oxovaleric acid (C13H10F6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
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), 5-(3,5-Ditrifluoromethylphenyl)-5-oxovaleric acid 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.
