Based on its molecular formula C14H20F2S2Si2, 3,3′-Difluoro-5,5′-bis(trimethylsilyl)-2,2′-bithiophene contains sulfur-containing functionality, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 346.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3,3′-Difluoro-5,5′-bis(trimethylsilyl)-2,2′-bithiophene (CAS 1619967-07-5), a certified reference material (molecular formula C14H20F2S2Si2, MW 346.61 g/mol) for analytical method development and quality control.
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.
