Chemical Structure
Description
The occurrence of 1-Ethyl-1-methylpyrrolidin-1-ium hexafluorophosphate(V) is closely related to organophosphorus functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Ethyl-1-methylpyrrolidin-1-ium hexafluorophosphate(V) (CAS 121057-90-7), molecular formula F6PC7H16N and molecular weight 259.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula F6PC7H16N, 1-Ethyl-1-methylpyrrolidin-1-ium hexafluorophosphate(V) contains organophosphorus functionality, fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 259.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
