(2E)-3-(2-Chlorophenyl)-1-(4-methoxyphenyl)prop-2-en-1-one CAS 5424-03-3

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.

(2E)-3-(2-Chlorophenyl)-1-(4-methoxyphenyl)prop-2-en-1-one (CAS 5424-03-3) is a high-purity analytical reference standard with the molecular formula C16H13ClO2 and a molecular weight of 272.73 g/mol.

The molecular framework of (2E)-3-(2-Chlorophenyl)-1-(4-methoxyphenyl)prop-2-en-1-one (C16H13ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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.

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.
