4-Amino-8-[3-[(3,4-dimethoxyphenethyl)amino]propyl]-6,6-dimethyl-2-(4-methyl-3-nitrophenyl)-3H-imidazo[4,5-h]isoquinoline-7,9(6H,8H)-dione (CAS 851658-10-1), molecular formula C32H36N6O6 and molecular weight 600.66 g/mol, is a CATO reference standard with documented purity and traceability.
4-Amino-8-[3-[(3,4-dimethoxyphenethyl)amino]propyl]-6,6-dimethyl-2-(4-methyl-3-nitrophenyl)-3H-imidazo[4,5-h]isoquinoline-7,9(6H,8H)-dione (C32H36N6O6) contains a nitrogen-containing heterocyclic scaffold, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
