Chemical Structure
Description
The molecular framework of 3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(3-methoxypropyl)-10-methyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C22H21ClN4O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(3-methoxypropyl)-10-methyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 606961-13-1) is a high-purity analytical reference standard with the molecular formula C22H21ClN4O4S and a molecular weight of 472.94 g/mol.
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.
