1-Butyl-1-methyl-1-pyrrolidinium Tetrafluoroborate CAS 345984-11-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Butyl-1-methyl-1-pyrrolidinium Tetrafluoroborate.

1-Butyl-1-methyl-1-pyrrolidinium Tetrafluoroborate (CAS 345984-11-4), molecular formula C9H20NBF4 and molecular weight 229.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H20NBF4, 1-Butyl-1-methyl-1-pyrrolidinium Tetrafluoroborate contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 229.07 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.
