Chemical Structure

1-Hexadecyl-3-methylimidazolium bromide CAS 132361-22-9 chemical structure

Description

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.

CATO supplies 1-Hexadecyl-3-methylimidazolium bromide (CAS 132361-22-9), a certified reference material (molecular formula C20H39N2Br, MW 387.45 g/mol) for analytical method development and quality control.

The molecular framework of 1-Hexadecyl-3-methylimidazolium bromide (C20H39N2Br) is characterized by a nitrile group, bromine 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.
