603-62-3 3-Nitrophthalimide 1H-Isoindole-1,3(2H)-dione, 4-nitro- AI3-08841 EINECS 210-051-2 NSC 5393 Phthalimide, 3-nitro- CAS 603-62-3 chemical structure

Description

603-62-3 3-Nitrophthalimide 1H-Isoindole-1,3(2H)-dione, 4-nitro- AI3-08841 EINECS 210-051-2 NSC 5393 Phthalimide, 3-nitro- (C8H10N2O4) contains an amino-acid-derived structure, 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).
