Description
(R)-1-(2,6-Diethylphenyl)-3-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) (CAS 1630817-21-8) is a high-purity analytical reference standard with the molecular formula C21H27N2OF6P and a molecular weight of 468.42 g/mol.
The molecular framework of (R)-1-(2,6-Diethylphenyl)-3-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) (C21H27N2OF6P) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
