Chemical Structure
Description
2-Aminobenzimidazole-5-carbonitrile (CAS 63655-40-3), molecular formula C8H6N4 and molecular weight 158.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Aminobenzimidazole-5-carbonitrile (C8H6N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 158.16 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.
CATO manufactures 2-Aminobenzimidazole-5-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
