Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,7-Difluro-3,6-bis[(2-methoxyethoxy)-methoxy]-9H-xanthen-9-one.
2,7-Difluro-3,6-bis[(2-methoxyethoxy)-methoxy]-9H-xanthen-9-one (CAS 430459-53-3) is a high-purity analytical reference standard with the molecular formula C21H22F2O8 and a molecular weight of 440.39 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution, 2,7-Difluro-3,6-bis[(2-methoxyethoxy)-methoxy]-9H-xanthen-9-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
