Compared with other compounds in its class, the molecular weight of 324.37 g/mol gives 5-Methoxy-2-(2-(pyrrolidin-1-yl)ethyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Methoxy-2-(2-(pyrrolidin-1-yl)ethyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione (CAS 69408-99-7) is a high-purity analytical reference standard with the molecular formula C19H20N2O3 and a molecular weight of 324.37 g/mol.
The molecular framework of 5-Methoxy-2-(2-(pyrrolidin-1-yl)ethyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione (C19H20N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
