Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(1h-Benzo[d]imidazol-2-yl)ethan-1-amine (CAS 73042-50-9), molecular formula C9H11N3 and molecular weight 161.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(1h-Benzo[d]imidazol-2-yl)ethan-1-amine (C9H11N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(1h-Benzo[d]imidazol-2-yl)ethan-1-amine 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.
