Chemical Structure

5-O-Methylvisammioside CAS 84272-85-5 chemical structure

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.

5-O-Methylvisammioside (CAS 84272-85-5) is a high-purity analytical reference standard with the molecular formula C22H28O10 and a molecular weight of 452.45 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 5-O-Methylvisammioside is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
