Chemical Structure
Description
The molecular framework of Glycine, N-[(1,1-dimethylethoxy)carbonyl]thio-L-phenylalanyl-, methyl ester (C17H24N2O4S) 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 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).
Glycine, N-[(1,1-dimethylethoxy)carbonyl]thio-L-phenylalanyl-, methyl ester (CAS 128421-85-2) is a high-purity analytical reference standard with the molecular formula C17H24N2O4S and a molecular weight of 352.45 g/mol.
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.
