The occurrence of 18-Hydroxy-7,19-dimethyl-20-methylene-2-(3-methylhexa-3,5-dien-1-yl)-22-oxooxacyclodocosa-4,6,12,14,16-pentaen-8-yl dihydrogen phosphate is closely related to a phosphate ester group, 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.
18-Hydroxy-7,19-dimethyl-20-methylene-2-(3-methylhexa-3,5-dien-1-yl)-22-oxooxacyclodocosa-4,6,12,14,16-pentaen-8-yl dihydrogen phosphate (CAS 95152-89-9), molecular formula C31H45O7P and molecular weight 560.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 18-Hydroxy-7,19-dimethyl-20-methylene-2-(3-methylhexa-3,5-dien-1-yl)-22-oxooxacyclodocosa-4,6,12,14,16-pentaen-8-yl dihydrogen phosphate (C31H45O7P) is characterized by a phosphate ester group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
