Chemical Structure
Description
(2E)-3-(2,5-Dimethoxyphenyl)-1-(2-methylphenyl)prop-2-en-1-one (CAS 1354941-48-2) 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)-3-(2,5-Dimethoxyphenyl)-1-(2-methylphenyl)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.
CATO manufactures (2E)-3-(2,5-Dimethoxyphenyl)-1-(2-methylphenyl)prop-2-en-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
