Chemical Structure
Description
Based on its molecular formula C18H27N5O21P4, Denufosol Tetrasodium contains a flavonoid core, an amide group, a phosphate ester group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 773.32 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).
Denufosol Tetrasodium (CAS 318250-11-2) is a high-purity analytical reference standard with the molecular formula C18H27N5O21P4 and a molecular weight of 773.32 g/mol.
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.
