Chemical Structure
Description
The molecular framework of 3-Hexyl-1-methyl-3-imidazolium Hydrogensulfate (C10H21N2HO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Hexyl-1-methyl-3-imidazolium Hydrogensulfate (CAS 478935-29-4), molecular formula C10H21N2HO4S and molecular weight 266.36 g/mol, is a CATO reference standard with documented purity and traceability.
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.
