5,5''-Bis(4'-fluoro-[1,1'-biphenyl]-4-yl)-2,2':5',2''-terthiophene CAS 1266111-48-1

Description

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.

5,5''-Bis(4'-fluoro-[1,1'-biphenyl]-4-yl)-2,2':5',2''-terthiophene (CAS 1266111-48-1) is a high-purity analytical reference standard with the molecular formula C36H22F2S3 and a molecular weight of 588.75 g/mol.

Based on its molecular formula C36H22F2S3, 5,5''-Bis(4'-fluoro-[1,1'-biphenyl]-4-yl)-2,2':5',2''-terthiophene contains sulfur-containing functionality, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 588.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
