Chemical Structure

(1aR,2E,4aR,6S,7S,7aS,8Z,11aS)-4a-Acetoxy-9-(acetoxymethyl)-1,1,3,6-tetramethyl-4-oxo-1a,4,4a,5,6,7,7a,10,11,11a-decahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl cinnamate CAS 93550-94-8 chemical structure

Description

The occurrence of (1aR,2E,4aR,6S,7S,7aS,8Z,11aS)-4a-Acetoxy-9-(acetoxymethyl)-1,1,3,6-tetramethyl-4-oxo-1a,4,4a,5,6,7,7a,10,11,11a-decahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl cinnamate 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.

(1aR,2E,4aR,6S,7S,7aS,8Z,11aS)-4a-Acetoxy-9-(acetoxymethyl)-1,1,3,6-tetramethyl-4-oxo-1a,4,4a,5,6,7,7a,10,11,11a-decahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl cinnamate (CAS 93550-94-8) is a high-purity analytical reference standard with the molecular formula C33H40O7 and a molecular weight of 548.67 g/mol.

The molecular framework of (1aR,2E,4aR,6S,7S,7aS,8Z,11aS)-4a-Acetoxy-9-(acetoxymethyl)-1,1,3,6-tetramethyl-4-oxo-1a,4,4a,5,6,7,7a,10,11,11a-decahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl cinnamate (C33H40O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
