Chemical Structure
Description
L-Glutamic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1-[2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]ethyl] 5-(1,1-dimethylethyl) ester (C32H40N2O10) 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).
