Chemical Structure
Description
(S)-5-((amino((tert-butoxycarbonyl)amino)methylene)amino)-2-(((benzyloxy)carbonyl)amino)pentanoic acid (CAS 2601-51-6), molecular formula C19H28N4O6 and molecular weight 408.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-5-((amino((tert-butoxycarbonyl)amino)methylene)amino)-2-(((benzyloxy)carbonyl)amino)pentanoic acid (C19H28N4O6) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
