Chemical Structure
Description
N6-(bis(ethylamino)methylene)-D-lysine TFA salt (C11H24N4O2C2HF3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N6-(bis(ethylamino)methylene)-D-lysine TFA salt (CAS 98500-82-4 (free base)), molecular formula C11H24N4O2C2HF3O2 and molecular weight 358.36 g/mol, is a CATO reference standard with documented purity and traceability.
