Chemical Structure
Description
5-Fluoro-7-nitro-2,3-dihydro-1h-indole-2,3-dione (C8H3FN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Fluoro-7-nitro-2,3-dihydro-1h-indole-2,3-dione (CAS 954571-39-2) is a high-purity analytical reference standard with the molecular formula C8H3FN2O4 and a molecular weight of 210.12 g/mol.
