(2E)-1-(4-Ethylphenyl)-3-(2-methylphenyl)prop-2-en-1-one CAS 1175843-88-5 chemical structure

Description

The occurrence of (2E)-1-(4-Ethylphenyl)-3-(2-methylphenyl)prop-2-en-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E)-1-(4-Ethylphenyl)-3-(2-methylphenyl)prop-2-en-1-one (CAS 1175843-88-5), a certified reference material (molecular formula C18H18O, MW 250.33 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, (2E)-1-(4-Ethylphenyl)-3-(2-methylphenyl)prop-2-en-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 250.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), (2E)-1-(4-Ethylphenyl)-3-(2-methylphenyl)prop-2-en-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
