Chemical Structure
Description
As a certified reference material (CRM), (2Z)-1-(2,4-Dichlorophenyl)-3-(dimethylamino)-2-(4-fluorobenzenesulfonyl)prop-2-en-1-one 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.
(2Z)-1-(2,4-Dichlorophenyl)-3-(dimethylamino)-2-(4-fluorobenzenesulfonyl)prop-2-en-1-one (CAS 344265-59-4) is a high-purity analytical reference standard with the molecular formula C17H14Cl2FNO3S and a molecular weight of 402.27 g/mol.
The molecular framework of (2Z)-1-(2,4-Dichlorophenyl)-3-(dimethylamino)-2-(4-fluorobenzenesulfonyl)prop-2-en-1-one (C17H14Cl2FNO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
