Description

Structurally, 108375-77-5 PC 766B Oxacyclohexadeca-3,5,11,13-tetraen-2-one, 16-((1S,2R,3S)-3-((2R,4R,5S,6R)-4-((2,6-dideoxy-beta-D-arabino-hexopyranosyl)oxy)tetrahydro-2-hydroxy-5-methyl-6-((1E,3E)-1,3-pentadienyl)-2H-pyran-2-yl)-2-hydroxy-1-methylbutyl)-8-hydroxy-3,15-dimethoxy-5,7,9,11-tetramethyl-, (3Z,5E,7R,8S,9S,11E,13E,15S,16R)- PC-766B (C43H68O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 776.99 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).
