CATO supplies (2R,3R,4S,5S,6R)-2-(Acetoxymethyl)-6-(((2R,3R,4S,5S,6S)-3,5-dihydroxy-2-(hydroxymethyl)-6-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 71978-78-4), a certified reference material (molecular formula C21H32O15, MW 524.47 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H32O15, (2R,3R,4S,5S,6R)-2-(Acetoxymethyl)-6-(((2R,3R,4S,5S,6S)-3,5-dihydroxy-2-(hydroxymethyl)-6-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 524.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
