Chemical Structure
Description
1,2-Bis(2-fluorophenyl)ethane (C14H12F2) contains fluorine substitution, a polycyclic aromatic 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1,2-Bis(2-fluorophenyl)ethane (CAS 349-38-2) is a high-purity analytical reference standard with the molecular formula C14H12F2 and a molecular weight of 218.24 g/mol.
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.
