Chemical Structure
Description
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.
CATO supplies Benzyl N-[(S)-1-Benzyl-2-(tosyloxy)ethyl]carbamate (CAS 194935-55-2), a certified reference material (molecular formula C24H25NO5S, MW 439.52 g/mol) for analytical method development and quality control.
The molecular framework of Benzyl N-[(S)-1-Benzyl-2-(tosyloxy)ethyl]carbamate (C24H25NO5S) is characterized by a flavonoid core, an amide group, a sulfone 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.
