Chemical Structure
Description
(3R,4S,5S,6S)-2-hydroxy-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl tris(2-methylpropanoate) (CAS 1190403-86-1) is a high-purity analytical reference standard with the molecular formula C19H30O10 and a molecular weight of 418.44 g/mol.
The molecular framework of (3R,4S,5S,6S)-2-hydroxy-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl tris(2-methylpropanoate) (C19H30O10) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
