Chemical Structure
Description
Based on its molecular formula C10H4Br2N4O4, 5,5'-Dibromo-3,3'-dinitro-2,2'-bipyridine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5,5'-Dibromo-3,3'-dinitro-2,2'-bipyridine (CAS 321844-96-6) is a high-purity analytical reference standard with the molecular formula C10H4Br2N4O4 and a molecular weight of 403.97 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
