10-(3,4-Dimethoxyphenyl)-3-heptyl-7-methyl-1,3,8,12-tetraazatricyclo[7.3.0.0^{2,6}]dodeca-2(6),7,9,11-tetraene (CAS 685108-52-5), molecular formula C24H32N4O2 and molecular weight 408.54 g/mol, is a CATO reference standard with documented purity and traceability.
10-(3,4-Dimethoxyphenyl)-3-heptyl-7-methyl-1,3,8,12-tetraazatricyclo[7.3.0.0^{2,6}]dodeca-2(6),7,9,11-tetraene (C24H32N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
