Chemical Structure
Description
H-Phe-Arg-OH (G-2865.0001) (C15H23N5O3C2HF3O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
H-Phe-Arg-OH (G-2865.0001) (CAS 1238-09-1), molecular formula C15H23N5O3C2HF3O2 and molecular weight 435.40 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
