Chemical Structure

Fmoc-Homoarg-OH CAS 776277-76-0 chemical structure

Description

Fmoc-Homoarg-OH (C22H26N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
