Chemical Structure
Description
<I>N</I>-(5-chloro-2-pyridyl)bis(trifluoromethanesulfonimide) (CAS 145100-51-2) is a high-purity analytical reference standard with the molecular formula C7H9ClF6N2O4S2 and a molecular weight of 398.73 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, <I>N</I>-(5-chloro-2-pyridyl)bis(trifluoromethanesulfonimide) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
