Chemical Structure
Description
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.
Bromo[tris(3,3,4,4,5,5,6,6,6-nonafluorohexyl)]stannane (CAS 240497-37-4) is a high-purity analytical reference standard with the molecular formula C18H12BrF27Sn and a molecular weight of 939.86 g/mol.
Structurally, Bromo[tris(3,3,4,4,5,5,6,6,6-nonafluorohexyl)]stannane (C18H12BrF27Sn) contains fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 939.86 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
