Chemical Structure

(2R,3S,4S,5R,6S)-2-(((tert-Butyldiphenylsilyl)oxy)methyl)-6-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl tribenzoate CAS 920975-58-2 chemical structure

Description

Based on its molecular formula C53H48O11Si, (2R,3S,4S,5R,6S)-2-(((tert-Butyldiphenylsilyl)oxy)methyl)-6-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl tribenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 889.03 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).
