Chemical Structure

(2E)-3-(4-Chlorophenyl)-1-(2,5-dimethoxyphenyl)prop-2-en-1-one CAS 1345675-59-3 chemical structure

Description

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.

CATO supplies (2E)-3-(4-Chlorophenyl)-1-(2,5-dimethoxyphenyl)prop-2-en-1-one (CAS 1345675-59-3), a certified reference material (molecular formula C17H15ClO3, MW 302.75 g/mol) for analytical method development and quality control.

The molecular framework of (2E)-3-(4-Chlorophenyl)-1-(2,5-dimethoxyphenyl)prop-2-en-1-one (C17H15ClO3) 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 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).

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.
