Chemical Structure
Description
3-(2,3-Dihydro-1H-inden-5-yl)-1-{1-[2-(2-methylphenyl)-2-oxoethyl]-2-oxo-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-3-yl}urea (C34H30N4O3) 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).
