Structurally, (2S,4S,5R,6R)-5-Acetamido-2-(((2R,3R,4S,5S,6R)-2-(((2S,3R,4R,5S,6R)-3-acetamido-2-(((2R,3S,4S,5R,6S)-2-((((2R,3R,4R,5S,6R)-3-acetamido-5-(((2S,3R,4S,5R,6R)-6-((((2R,4S,5R,6R)-5-acetamido-2-carboxy-4-hydroxy-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-yl)oxy)methyl)-3,4,5-trihydroxytetrahydro-2H-pyran-2-yl)oxy)-4-hydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)methyl)-3,5-dihydroxy-6-(((2R,3R,4R,5R)-1,2,4,5-tetrahydroxy-6-oxohexan-3-yl)oxy)tetrahydro-2H-pyran-4-yl)oxy)-5-hydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-4-yl)oxy)-3,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-4-yl)oxy)-4-hydroxy-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylic acid (C62H102N4O47) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 1655.47 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).

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.
