1-Fluoro-4-{[(4-{[(4-fluorophenyl)sulfanyl]methyl}phenyl)methyl]sulfanyl}benzene CAS 478258-28-5

Description

Based on its molecular formula C20H16F2S2, 1-Fluoro-4-{[(4-{[(4-fluorophenyl)sulfanyl]methyl}phenyl)methyl]sulfanyl}benzene 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 358.47 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.

1-Fluoro-4-{[(4-{[(4-fluorophenyl)sulfanyl]methyl}phenyl)methyl]sulfanyl}benzene (CAS 478258-28-5), molecular formula C20H16F2S2 and molecular weight 358.47 g/mol, is a CATO reference standard with documented purity and traceability.

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.
