Chemical Structure
Description
1-Bromo-3-fluoro-2-methoxy-4-nitrobenzene (CAS 1224629-07-5) is a high-purity analytical reference standard with the molecular formula C7H5BrFNO3 and a molecular weight of 250.02 g/mol.
Based on its molecular formula C7H5BrFNO3, 1-Bromo-3-fluoro-2-methoxy-4-nitrobenzene contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.02 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).
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.
