Chemical Structure
Description
N2-(((9H-fluoren-9-yl)methoxy)carbonyl)-N6-(3,7-dioxo-1,9-diphenyl-2,8-dioxa-4,6-diazanonan-5-ylidene)lysine (C38H38N4O8) 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).
N2-(((9H-fluoren-9-yl)methoxy)carbonyl)-N6-(3,7-dioxo-1,9-diphenyl-2,8-dioxa-4,6-diazanonan-5-ylidene)lysine (CAS 2044709-94-4), molecular formula C38H38N4O8 and molecular weight 678.73 g/mol, is a CATO reference standard with documented purity and traceability.
