Chemical Structure
Description
The occurrence of ((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-methoxytetrahydro-2H-pyran-2-yl)methyl benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-methoxytetrahydro-2H-pyran-2-yl)methyl benzoate (CAS 4338-28-7) is a high-purity analytical reference standard with the molecular formula C14H18O7 and a molecular weight of 298.29 g/mol.
Structurally, ((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-methoxytetrahydro-2H-pyran-2-yl)methyl benzoate (C14H18O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 298.29 g/mol, it falls into the medium-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).
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.
