The occurrence of Methyl (4aS,6aR,6bS,8aR,10S,12aS,14aR,14bS)-10-hydroxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate 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.
Methyl (4aS,6aR,6bS,8aR,10S,12aS,14aR,14bS)-10-hydroxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate (CAS 65023-19-0), molecular formula C31H48O4 and molecular weight 484.71 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl (4aS,6aR,6bS,8aR,10S,12aS,14aR,14bS)-10-hydroxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate (C31H48O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
