Chemical Structure
Description
Based on its molecular formula C50H71N13O12, Angiotensin II contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1046.19 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).
Angiotensin II (CAS 4474-91-3), molecular formula C50H71N13O12 and molecular weight 1046.19 g/mol, is a CATO reference standard with documented purity and traceability.
