Chemical Structure

3-Ethyl-1-methyl-1H-imidazol-3-ium methanesulfonate CAS 145022-45-3 chemical structure

Description

CATO supplies 3-Ethyl-1-methyl-1H-imidazol-3-ium methanesulfonate (CAS 145022-45-3), a certified reference material (molecular formula C6H11N2CH3O3S, MW 206.26 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Ethyl-1-methyl-1H-imidazol-3-ium methanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 manufactures 3-Ethyl-1-methyl-1H-imidazol-3-ium methanesulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
