Description
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.
3-((4-Chlorophenyl)sulfonyl)-2-imino-10-methyl-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 577987-20-3) is a high-purity analytical reference standard with the molecular formula C24H18ClN5O3S and a molecular weight of 491.95 g/mol.
3-((4-Chlorophenyl)sulfonyl)-2-imino-10-methyl-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C24H18ClN5O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
