Description

Structurally, (2R,3R,4S,5R,6R)-3,4,5-tris(benzyloxy)-6-((benzyloxy)methyl)-2-(dichloromethyl)tetrahydro-2H-pyran-2-ol (C35H36Cl2O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 623.56 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).
