Chemical Structure
Description
The occurrence of 1,5-Difluoro-2-iodo-4-nitrobenzene is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Difluoro-2-iodo-4-nitrobenzene (CAS 148388-74-3) is a high-purity analytical reference standard with the molecular formula C6H2F2INO2 and a molecular weight of 284.99 g/mol.
1,5-Difluoro-2-iodo-4-nitrobenzene (C6H2F2INO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. 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.
