Chemical Structure
Description
The occurrence of Tetramethylammonium (tetrafluoroborate) is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetramethylammonium (tetrafluoroborate) (CAS 661-36-9), molecular formula BF4C4H12N and molecular weight 160.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetramethylammonium (tetrafluoroborate) (BF4C4H12N) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Tetramethylammonium (tetrafluoroborate) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
