Chemical Structure

4-Methyl-5-(p-tolyl)-1H-imidazole CAS 439931-81-4 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-5-(p-tolyl)-1H-imidazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 172.23 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).

4-Methyl-5-(p-tolyl)-1H-imidazole (CAS 439931-81-4), molecular formula C11H12N2 and molecular weight 172.23 g/mol, is a CATO reference standard with documented purity and traceability.

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