Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl ((S)-1-((2-(((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)amino)-2-oxoethyl)amino)-4-methyl-1-oxopentan-2-yl)carbamate hydrochloride.

tert-Butyl ((S)-1-((2-(((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)amino)-2-oxoethyl)amino)-4-methyl-1-oxopentan-2-yl)carbamate hydrochloride (CAS 71730-95-5), molecular formula C25H40N8O7HCl and molecular weight 601.10 g/mol, is a CATO reference standard with documented purity and traceability.

tert-Butyl ((S)-1-((2-(((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)amino)-2-oxoethyl)amino)-4-methyl-1-oxopentan-2-yl)carbamate hydrochloride (C25H40N8O7HCl) 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).

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.
