(R)-4-Nitrobenzyl 4-amino-2-(((benzyloxy)carbonyl)amino)-4-oxobutanoate CAS 58578-32-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-4-Nitrobenzyl 4-amino-2-(((benzyloxy)carbonyl)amino)-4-oxobutanoate.

(R)-4-Nitrobenzyl 4-amino-2-(((benzyloxy)carbonyl)amino)-4-oxobutanoate (CAS 58578-32-8) is a high-purity analytical reference standard with the molecular formula C19H19N3O7 and a molecular weight of 401.37 g/mol.

The molecular framework of (R)-4-Nitrobenzyl 4-amino-2-(((benzyloxy)carbonyl)amino)-4-oxobutanoate (C19H19N3O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
