Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.00 g/mol gives 5-Bromo-2-nitronicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-nitronicotinic acid (CAS 1807273-49-9) is a high-purity analytical reference standard with the molecular formula C6H3BrN2O4 and a molecular weight of 247.00 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 5-Bromo-2-nitronicotinic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
