3,3',5,5'-Tetrafluoro-[1,1'-biphenyl]-4,4'-dicarboxylic acid CAS 31381-91-6

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 3,3',5,5'-Tetrafluoro-[1,1'-biphenyl]-4,4'-dicarboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

3,3',5,5'-Tetrafluoro-[1,1'-biphenyl]-4,4'-dicarboxylic acid (CAS 31381-91-6) is a high-purity analytical reference standard with the molecular formula C14H6F4O4 and a molecular weight of 314.19 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.
