(S)-2-((S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-6-yl)propanamido)-5-guanidinopentanamide xhydrochloride (CAS 83363-71-7) is a high-purity analytical reference standard with the molecular formula C19H26N6O4HCl and a molecular weight of 438.91 g/mol.
(S)-2-((S)-2-Amino-N-(4-methyl-2-oxo-2H-chromen-6-yl)propanamido)-5-guanidinopentanamide xhydrochloride (C19H26N6O4HCl) contains a flavonoid core, an amide 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).
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.
