Chemical Structure
Description
Acetyldiethylstilbestrol 2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester (CAS 40269-22-5) is a high-purity analytical reference standard with the molecular formula C33H38O12 and a molecular weight of 626.65 g/mol.
Structurally, Acetyldiethylstilbestrol 2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester (C33H38O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 626.65 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).
