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-Fluoro-N-(triphenylphosphoranylidene)benzenesulfonamide (CAS 105899-98-7) is a high-purity analytical reference standard with the molecular formula C24H19FNO2PS and a molecular weight of 435.45 g/mol.
4-Fluoro-N-(triphenylphosphoranylidene)benzenesulfonamide (C24H19FNO2PS) contains a steroid core, an amide group, a sulfone group, organophosphorus functionality, 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, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 4-Fluoro-N-(triphenylphosphoranylidene)benzenesulfonamide 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.
