Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4’-Diamino-2,2’-dibromobiphenyl (CAS 84530-60-9), molecular formula C12H10Br2N2 and molecular weight 342.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H10Br2N2, 4,4’-Diamino-2,2’-dibromobiphenyl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.03 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).
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.
