Chemical Structure
Description
The molecular framework of Cyclo(-Gly-Tyr(PO3H2)-Val-Pro-Met-Leu) (C32H49N6O10PS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
