4',4''',4''''',4'''''''-(Ethene-1,1,2,2-tetrayl)tetrakis(3-fluoro-[1,1'-biphenyl]-4-carboxylicacid) (CAS 1643112-48-4), molecular formula C54H32F4O8 and molecular weight 884.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4',4''',4''''',4'''''''-(Ethene-1,1,2,2-tetrayl)tetrakis(3-fluoro-[1,1'-biphenyl]-4-carboxylicacid) (C54H32F4O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
