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.
N2-(tert-butoxycarbonyl)-N6-(2,2,2-trifluoroacetyl)-D-lysine (CAS 96561-04-5) is a high-purity analytical reference standard with the molecular formula C13H21F3N2O5 and a molecular weight of 342.31 g/mol.
The molecular framework of N2-(tert-butoxycarbonyl)-N6-(2,2,2-trifluoroacetyl)-D-lysine (C13H21F3N2O5) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. 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.
