Chemical Structure

H-L-Leu-L-Lys-γ-Pip-OH CAS CATO-CPTD788740 chemical structure

Description

Based on its molecular formula C18H35N5O4, H-L-Leu-L-Lys-γ-Pip-OH contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 385.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
