Chemical Structure
Description
The molecular framework of (2Z)-2-(Benzenesulfonyl)-1-(2,4-dichlorophenyl)-3-(dimethylamino)prop-2-en-1-one (C17H15Cl2NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. 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).
(2Z)-2-(Benzenesulfonyl)-1-(2,4-dichlorophenyl)-3-(dimethylamino)prop-2-en-1-one (CAS 1164528-38-4), molecular formula C17H15Cl2NO3S and molecular weight 384.28 g/mol, is a CATO reference standard with documented purity and traceability.
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), (2Z)-2-(Benzenesulfonyl)-1-(2,4-dichlorophenyl)-3-(dimethylamino)prop-2-en-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
