Chemical Structure
Description
The molecular framework of CKS-17 (7-12) H-Leu-Asp-Leu-Leu-Phe-Leu-OH (C37H60N6O9) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
CKS-17 (7-12) H-Leu-Asp-Leu-Leu-Phe-Leu-OH (CAS 141975-99-7) is a high-purity analytical reference standard with the molecular formula C37H60N6O9 and a molecular weight of 732.91 g/mol.
