Chemical Structure
Description
(2E)-3-(2,4-Dichlorophenyl)-1-(2,5-dimethoxyphenyl)prop-2-en-1-one (CAS 219488-08-1), molecular formula C17H14Cl2O3 and molecular weight 337.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-3-(2,4-Dichlorophenyl)-1-(2,5-dimethoxyphenyl)prop-2-en-1-one (C17H14Cl2O3) is characterized by a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (2E)-3-(2,4-Dichlorophenyl)-1-(2,5-dimethoxyphenyl)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.
