Chemical Structure
Description
4-fluoro-7-nitro-1H-indazole (C7H12FN3O2) contains an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-fluoro-7-nitro-1H-indazole (CAS 866144-02-7) is a high-purity analytical reference standard with the molecular formula C7H12FN3O2 and a molecular weight of 189.19 g/mol.
