Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.19 g/mol gives 1,3-Difluoro-5-(3-nitrophenyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Difluoro-5-(3-nitrophenyl)benzene (CAS 865856-72-0) is a high-purity analytical reference standard with the molecular formula C12H7F2NO2 and a molecular weight of 235.19 g/mol.
Based on its molecular formula C12H7F2NO2, 1,3-Difluoro-5-(3-nitrophenyl)benzene contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 235.19 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.
