Chemical Structure
Description
1-(2-Chlorophenoxy)-3-(4-fluorobenzenesulfonyl)propan-2-ol (CAS 478079-91-3), molecular formula C15H14ClFO4S and molecular weight 344.79 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Chlorophenoxy)-3-(4-fluorobenzenesulfonyl)propan-2-ol (C15H14ClFO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1-(2-Chlorophenoxy)-3-(4-fluorobenzenesulfonyl)propan-2-ol 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.
