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.
1-Allyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide (CAS 655249-87-9) is a high-purity analytical reference standard with the molecular formula C2F6NO4S2C7H11N2 and a molecular weight of 403.31 g/mol.
Structurally, 1-Allyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide (C2F6NO4S2C7H11N2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 403.31 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
