Description

The occurrence of 144765-80-0 b-D-Glucopyranoside,2-(3,4-dimethoxyphenyl)ethyl 3-O-(2,3,4-tri-O-acetyl-6-deoxy-a-L-mannopyranosyl)-,2,6-diacetate 4-[3-[3,4-bis(acetyloxy)phenyl]-2-propenoate], (E)- (9CI) 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.

144765-80-0 b-D-Glucopyranoside,2-(3,4-dimethoxyphenyl)ethyl 3-O-(2,3,4-tri-O-acetyl-6-deoxy-a-L-mannopyranosyl)-,2,6-diacetate 4-[3-[3,4-bis(acetyloxy)phenyl]-2-propenoate], (E)- (9CI) (CAS 144765-80-0), molecular formula C45H54O22 and molecular weight 946.90 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 144765-80-0 b-D-Glucopyranoside,2-(3,4-dimethoxyphenyl)ethyl 3-O-(2,3,4-tri-O-acetyl-6-deoxy-a-L-mannopyranosyl)-,2,6-diacetate 4-[3-[3,4-bis(acetyloxy)phenyl]-2-propenoate], (E)- (9CI) (C45H54O22) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 946.90 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).
