Chemical Structure

(Sar1,Ile4·8)-Angiotensin II CAS 185461-45-4 chemical structure

Description

The molecular framework of (Sar1,Ile4·8)-Angiotensin II (C43H75N13O9) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
