Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 435.47 g/mol gives 1-(2,4-Dimethoxyphenyl)-3-(6-methoxy-3,4-dihydro-1H-pyrido[3,4-b]indol-2(9H)-yl)pyrrolidine-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(2,4-Dimethoxyphenyl)-3-(6-methoxy-3,4-dihydro-1H-pyrido[3,4-b]indol-2(9H)-yl)pyrrolidine-2,5-dione (CAS 1169874-04-7), a certified reference material (molecular formula C24H25N3O5, MW 435.47 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2,4-Dimethoxyphenyl)-3-(6-methoxy-3,4-dihydro-1H-pyrido[3,4-b]indol-2(9H)-yl)pyrrolidine-2,5-dione (C24H25N3O5) is characterized by a flavonoid 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.
