methyl (1S,4aR,6S,7R,7aS)-4a,7-dihydroxy-6-(((E)-3-(4-methoxyphenyl)acryloyl)oxy)-7-methyl-1-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-4-carboxylate (CAS 53526-66-2) is a high-purity analytical reference standard with the molecular formula C27H34O14 and a molecular weight of 582.55 g/mol.

methyl (1S,4aR,6S,7R,7aS)-4a,7-dihydroxy-6-(((E)-3-(4-methoxyphenyl)acryloyl)oxy)-7-methyl-1-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-4-carboxylate (C27H34O14) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
