Chemical Structure
Description
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.
1-Fluoro-4-isopropenylbenzene 2-(4-Fluorophenyl)propene 350-40-3 4-Fluoro-.alpha.-methylstyrene Benzene, 1-fluoro-4-(1-methylethenyl)- NSC-74474 NSC74474 Styrene, p-fluoro-.alpha.-methyl- p-Fluoro-.alpha.-methylstyrene (CAS 350-40-3) is a high-purity analytical reference standard with the molecular formula C9H15F and a molecular weight of 142.21 g/mol.
Based on its molecular formula C9H15F, 1-Fluoro-4-isopropenylbenzene 2-(4-Fluorophenyl)propene 350-40-3 4-Fluoro-.alpha.-methylstyrene Benzene, 1-fluoro-4-(1-methylethenyl)- NSC-74474 NSC74474 Styrene, p-fluoro-.alpha.-methyl- p-Fluoro-.alpha.-methylstyrene contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 142.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
