Chemical Structure
Description
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.
(S)-Benzyl 2-amino-6-((((2-chlorobenzyl)oxy)carbonyl)amino)hexanoate hydrochloride (CAS 201008-12-0), molecular formula C21H25ClN2O4HCl and molecular weight 441.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-Benzyl 2-amino-6-((((2-chlorobenzyl)oxy)carbonyl)amino)hexanoate hydrochloride (C21H25ClN2O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
