Chemical Structure
Description
The occurrence of (2Z)-2-(Benzenesulfonyl)-1-(3,4-dichlorophenyl)-3-(dimethylamino)prop-2-en-1-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2Z)-2-(Benzenesulfonyl)-1-(3,4-dichlorophenyl)-3-(dimethylamino)prop-2-en-1-one (CAS 344266-98-4), molecular formula C17H15Cl2NO3S and molecular weight 384.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2Z)-2-(Benzenesulfonyl)-1-(3,4-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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (2Z)-2-(Benzenesulfonyl)-1-(3,4-dichlorophenyl)-3-(dimethylamino)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.
