The occurrence of H-Leu-Lys-Leu-OH is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies H-Leu-Lys-Leu-OH (CAS 108241-43-6), a certified reference material (molecular formula C18H36N4O4, MW 372.50 g/mol) for analytical method development and quality control.
The molecular framework of H-Leu-Lys-Leu-OH (C18H36N4O4) is characterized by an amide group, a carboxylic acid 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).
