Chemical Structure
Description
The molecular framework of Ac-Arg-Cys-Met-5-aminopentanoyl-Arg-Val-Tyr-5-aminopentanoyl-Cys-NH2 trifluoroacetate salt (Disulfide bond) (C49H82N16O11S3C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
Ac-Arg-Cys-Met-5-aminopentanoyl-Arg-Val-Tyr-5-aminopentanoyl-Cys-NH2 trifluoroacetate salt (Disulfide bond) (CAS 353487-64-6), molecular formula C49H82N16O11S3C2HF3O2 and molecular weight 1281.50 g/mol, is a CATO reference standard with documented purity and traceability.
