Chemical Structure
Description
The occurrence of 3,3'-Di-O-methylellagic acid 4'-xylopyranoside is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,3'-Di-O-methylellagic acid 4'-xylopyranoside (CAS 62218-23-9) is a high-purity analytical reference standard with the molecular formula C21H30O12 and a molecular weight of 474.46 g/mol.
Based on its molecular formula C21H30O12, 3,3'-Di-O-methylellagic acid 4'-xylopyranoside 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 474.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
