2,2',3,3',4,4',5,5'-Octafluoro-1,1'-biphenyl CAS 5121-90-4

Description

Compared with other compounds in its class, the molecular weight of 298.13 g/mol gives 2,2',3,3',4,4',5,5'-Octafluoro-1,1'-biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,2',3,3',4,4',5,5'-Octafluoro-1,1'-biphenyl (CAS 5121-90-4) is a high-purity analytical reference standard with the molecular formula C12H2F8 and a molecular weight of 298.13 g/mol.

2,2',3,3',4,4',5,5'-Octafluoro-1,1'-biphenyl (C12H2F8) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
