Chemical Structure
Description
The occurrence of 3-((4-Chlorophenyl)sulfonyl)-1-cyclopentyl-2-imino-8-methyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-((4-Chlorophenyl)sulfonyl)-1-cyclopentyl-2-imino-8-methyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 606956-05-2), a certified reference material (molecular formula C23H21ClN4O3S, MW 468.96 g/mol) for analytical method development and quality control.
The molecular framework of 3-((4-Chlorophenyl)sulfonyl)-1-cyclopentyl-2-imino-8-methyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C23H21ClN4O3S) is characterized by a steroid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
