Chemical Structure
Description
The molecular framework of (2E)-1-(3,4-Dichlorophenyl)-3-[4-(propan-2-yl)phenyl]prop-2-en-1-one (C18H16Cl2O) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(2E)-1-(3,4-Dichlorophenyl)-3-[4-(propan-2-yl)phenyl]prop-2-en-1-one (CAS 1354941-70-0), molecular formula C18H16Cl2O and molecular weight 319.23 g/mol, is a CATO reference standard with documented purity and traceability.
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)-1-(3,4-Dichlorophenyl)-3-[4-(propan-2-yl)phenyl]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.
