Chemical Structure

5-Isocyanato-1-methyl-1H-imidazole CAS 499770-99-9 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, 5-Isocyanato-1-methyl-1H-imidazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 5-Isocyanato-1-methyl-1H-imidazole (CAS 499770-99-9), a certified reference material (molecular formula C5H5N3O, MW 123.11 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
