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.
(S)-3-(1-Hydroxy-4-methylpentan-2-yl)-1-mesityl-1H-imidazol-3-ium hexafluorophosphate(V) (CAS 1788856-01-8), molecular formula C18H27N2OF6P and molecular weight 432.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-3-(1-Hydroxy-4-methylpentan-2-yl)-1-mesityl-1H-imidazol-3-ium hexafluorophosphate(V) (C18H27N2OF6P) is characterized by an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, 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).
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.
