3'-Hydroxy-5,7,4'-trimethoxyflavone CAS 33554-52-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Hydroxy-5,7,4'-trimethoxyflavone.

CATO supplies 3'-Hydroxy-5,7,4'-trimethoxyflavone (CAS 33554-52-8), a certified reference material (molecular formula C18H16O6, MW 328.32 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H16O6, 3'-Hydroxy-5,7,4'-trimethoxyflavone contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 328.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
