Chemical Structure
Description
(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((diphenyl(p-tolyl)methyl)amino)pentanoic acid (C40H38N2O4) contains a nitrogen-containing heterocyclic scaffold, 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).
