Chemical Structure
Description
The occurrence of 1-(Pyrimidin-2-yl)-1H-imidazol-5(4H)-imine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(Pyrimidin-2-yl)-1H-imidazol-5(4H)-imine (CAS 88945-45-3), a certified reference material (molecular formula C7H7N5, MW 161.16 g/mol) for analytical method development and quality control.
Owing to a nitrile group, an aromatic ring system, 1-(Pyrimidin-2-yl)-1H-imidazol-5(4H)-imine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.16 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-(Pyrimidin-2-yl)-1H-imidazol-5(4H)-imine 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.
