Chemical Structure
Description
The occurrence of Z-Arg-p-nitrobenzyl ester (C-1300.0250) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Z-Arg-p-nitrobenzyl ester (C-1300.0250) (CAS 96723-72-7), molecular formula C21H25N5O6HCl and molecular weight 479.92 g/mol, is a CATO reference standard with documented purity and traceability.
Z-Arg-p-nitrobenzyl ester (C-1300.0250) (C21H25N5O6HCl) 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.
