Chemical Structure
Description
The occurrence of Tetrakis(pentafluorophenyl)stannane is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetrakis(pentafluorophenyl)stannane (CAS 1065-49-2) is a high-purity analytical reference standard with the molecular formula C24F20Sn and a molecular weight of 786.93 g/mol.
Based on its molecular formula C24F20Sn, Tetrakis(pentafluorophenyl)stannane contains fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 786.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
