383-29-9 Benzene, 1,1'-sulfonylbis(4-fluoro- Bis(p-fluorophenyl)sulphone Sulfone, bis(p-fluorophenyl) (8CI) Bis(p-fluorophenyl) sulfone Bis(4-fluorophenyl)sulfone 4,4'-Difluorodiphenyl sulfone EINECS 206-847-4 4-Fluorophenylsulfone NSC 87584 NSC 683542 (CAS 383-29-9) is a high-purity analytical reference standard with the molecular formula C12H20F2O2S and a molecular weight of 266.35 g/mol.
Structurally, 383-29-9 Benzene, 1,1'-sulfonylbis(4-fluoro- Bis(p-fluorophenyl)sulphone Sulfone, bis(p-fluorophenyl) (8CI) Bis(p-fluorophenyl) sulfone Bis(4-fluorophenyl)sulfone 4,4'-Difluorodiphenyl sulfone EINECS 206-847-4 4-Fluorophenylsulfone NSC 87584 NSC 683542 (C12H20F2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 266.35 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
