Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Chloro-2,3-dibromonitrobenzene (CAS 96558-77-9), a certified reference material (molecular formula C6H2Br2ClNO2, MW 315.35 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H2Br2ClNO2, 5-Chloro-2,3-dibromonitrobenzene contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.35 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.
