Chemical Structure
Description
1-Butyl-3-(2-pyridinylmethyl)-1H-imidazolium hexafluorophosphate (CAS 873788-09-1), molecular formula C13H18N3F6P and molecular weight 361.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Butyl-3-(2-pyridinylmethyl)-1H-imidazolium hexafluorophosphate (C13H18N3F6P) is characterized by a nitrile group, organophosphorus functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1-Butyl-3-(2-pyridinylmethyl)-1H-imidazolium hexafluorophosphate 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.
