Chemical Structure
Description
As a certified reference material (CRM), 5-Chloro-1-methyl-2-phenyl-1H-imidazole 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.
CATO supplies 5-Chloro-1-methyl-2-phenyl-1H-imidazole (CAS 7666-52-6), a certified reference material (molecular formula C10H9ClN2, MW 192.64 g/mol) for analytical method development and quality control.
Structurally, 5-Chloro-1-methyl-2-phenyl-1H-imidazole (C10H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 192.64 g/mol, it falls into the medium-molecular-weight range. 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.
