Chemical Structure

1,3-Dimethyl-3-imidazolium Iodide CAS 4333-62-4 chemical structure

Description

Based on its molecular formula IC5H9N2, 1,3-Dimethyl-3-imidazolium Iodide contains a nitrile group, iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 224.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 1,3-Dimethyl-3-imidazolium Iodide (CAS 4333-62-4), a certified reference material (molecular formula IC5H9N2, MW 224.04 g/mol) for analytical method development and quality control.

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.
