Description

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.

(2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(((2R,3S,4S,5R,6S)-3,5-diacetoxy-2-(acetoxymethyl)-6-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 145251-15-6) is a high-purity analytical reference standard with the molecular formula C27H38O18 and a molecular weight of 650.58 g/mol.

Structurally, (2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(((2R,3S,4S,5R,6S)-3,5-diacetoxy-2-(acetoxymethyl)-6-methoxytetrahydro-2H-pyran-4-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (C27H38O18) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 650.58 g/mol, it falls into the high-molecular-weight range. 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).
