Chemical Structure

3-Decyl-1,2-dimethyl-1H-imidazol-3-ium bromide CAS 21054-79-5 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.

CATO supplies 3-Decyl-1,2-dimethyl-1H-imidazol-3-ium bromide (CAS 21054-79-5), a certified reference material (molecular formula C15H29N2Br, MW 317.31 g/mol) for analytical method development and quality control.

The molecular framework of 3-Decyl-1,2-dimethyl-1H-imidazol-3-ium bromide (C15H29N2Br) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
