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-(((9H-fluoren-9-yl)methoxy)carbonyl)-N6-(2-(tert-butoxy)-2-oxoethyl)-N6-(tert-butoxycarbonyl)-L-lysine (CAS 866602-35-9), molecular formula C32H42N2O8 and molecular weight 582.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N2-(((9H-fluoren-9-yl)methoxy)carbonyl)-N6-(2-(tert-butoxy)-2-oxoethyl)-N6-(tert-butoxycarbonyl)-L-lysine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 582.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
