Nα,Nε-Bis(2,4-dinitrophenyl)-L-lysine (CAS 1655-49-8), molecular formula C18H18N6O10 and molecular weight 478.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Nα,Nε-Bis(2,4-dinitrophenyl)-L-lysine (C18H18N6O10) is characterized by a flavonoid core, an amide 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
