Chemical Structure
Description
The molecular framework of 5-[(1E)-2-(4-Hydroxyphenyl)ethenyl]-2-(phenylmethyl)-1,3-benzenediol (C21H18O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).
5-[(1E)-2-(4-Hydroxyphenyl)ethenyl]-2-(phenylmethyl)-1,3-benzenediol (CAS 1610531-11-7) is a high-purity analytical reference standard with the molecular formula C21H18O3 and a molecular weight of 318.37 g/mol.
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.
