Chemical Structure
Description
The occurrence of Purpureaglycoside A CRS is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Purpureaglycoside A CRS (CAS 19855-40-4) is a high-purity analytical reference standard with the molecular formula C47H74O18 and a molecular weight of 927.08 g/mol.
Structurally, Purpureaglycoside A CRS (C47H74O18) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 927.08 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).
