Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-1H-imidazole-5-carbonitrile.
CATO supplies 4-Chloro-1H-imidazole-5-carbonitrile (CAS 1333380-68-9), a certified reference material (molecular formula C4H2ClN3, MW 127.53 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H2ClN3, 4-Chloro-1H-imidazole-5-carbonitrile contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 127.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-Chloro-1H-imidazole-5-carbonitrile 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.
