Description
As a certified reference material (CRM), 4-Cyclopropyl-1H-imidazole-2-carbonitrile hydrochloride 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 4-Cyclopropyl-1H-imidazole-2-carbonitrile hydrochloride (CAS 2173991-69-8), a certified reference material (molecular formula C7H7N3HCl, MW 169.61 g/mol) for analytical method development and quality control.
The molecular framework of 4-Cyclopropyl-1H-imidazole-2-carbonitrile hydrochloride (C7H7N3HCl) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
