Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 420.02 g/mol gives 4-Bromo-N-(2-fluoro-4-iodophenyl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-N-(2-fluoro-4-iodophenyl)benzamide (CAS 903775-72-4) is a high-purity analytical reference standard with the molecular formula C13H8BrFINO and a molecular weight of 420.02 g/mol.
Based on its molecular formula C13H8BrFINO, 4-Bromo-N-(2-fluoro-4-iodophenyl)benzamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 420.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
