Chemical Structure
Description
The molecular framework of (E/Z)-1-[4-(2-Chloroethoxy)phenyl]-1-(4-hydroxyphenyl)-2-phenyl-1-butene (C24H23ClO2) 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.
(E/Z)-1-[4-(2-Chloroethoxy)phenyl]-1-(4-hydroxyphenyl)-2-phenyl-1-butene (CAS 119757-57-2), molecular formula C24H23ClO2 and molecular weight 378.89 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), (E/Z)-1-[4-(2-Chloroethoxy)phenyl]-1-(4-hydroxyphenyl)-2-phenyl-1-butene 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.
