Chemical Structure

(2E)-1-(4-Ethoxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-one CAS 158575-01-0 chemical structure

Description

(2E)-1-(4-Ethoxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-one (CAS 158575-01-0) is a high-purity analytical reference standard with the molecular formula C18H18O3 and a molecular weight of 282.33 g/mol.

The molecular framework of (2E)-1-(4-Ethoxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-one (C18H18O3) 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
