Description
CATO supplies 3,4-Difluoro-3-(2,5-dimethylphenyl)propiophenone (CAS 898754-08-0), a certified reference material (molecular formula C17H16F2O, MW 274.31 g/mol) for analytical method development and quality control.
3,4-Difluoro-3-(2,5-dimethylphenyl)propiophenone (C17H16F2O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3,4-Difluoro-3-(2,5-dimethylphenyl)propiophenone 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.
