Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Cyanophenyl)-3-methyl-1H-imidazol-3-ium iodide.
1-(2-Cyanophenyl)-3-methyl-1H-imidazol-3-ium iodide (CAS 321385-64-2), molecular formula C11H10N3I and molecular weight 311.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 1-(2-Cyanophenyl)-3-methyl-1H-imidazol-3-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.12 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(2-Cyanophenyl)-3-methyl-1H-imidazol-3-ium iodide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
