Chemical Structure
Description
The occurrence of 3-Ethyl-1-vinyl-1H-imidazol-3-ium iodide is closely related to a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Ethyl-1-vinyl-1H-imidazol-3-ium iodide (CAS 81517-60-4), a certified reference material (molecular formula IC7H11N2, MW 250.08 g/mol) for analytical method development and quality control.
Owing to a nitrile group, iodine substitution, 3-Ethyl-1-vinyl-1H-imidazol-3-ium iodide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
