1,3-Isobenzofurandione, polymer with 1,2-ethanediol, [tetradecahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenyl]methyl ester (CAS 70775-80-3), molecular formula C20H36OC8H4O3C2H6O2 and molecular weight 502.69 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Isobenzofurandione, polymer with 1,2-ethanediol, [tetradecahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenyl]methyl ester (C20H36OC8H4O3C2H6O2) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
