(2E)-1-(3-Methoxyphenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one CAS 1287289-48-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-1-(3-Methoxyphenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one.

CATO supplies (2E)-1-(3-Methoxyphenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one (CAS 1287289-48-8), a certified reference material (molecular formula C19H20O5, MW 328.36 g/mol) for analytical method development and quality control.

Structurally, (2E)-1-(3-Methoxyphenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one (C19H20O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 328.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
