Chemical Structure
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.
2,5-Bis(trimethylsilyl)-1,4-phenylene Bis(trifluoromethanesulfonate) (CAS 613676-07-6) is a high-purity analytical reference standard with the molecular formula C14H20F6O6S2Si2 and a molecular weight of 518.60 g/mol.
Structurally, 2,5-Bis(trimethylsilyl)-1,4-phenylene Bis(trifluoromethanesulfonate) (C14H20F6O6S2Si2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 518.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.
