Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 175.23 g/mol gives 2-(3-Aminopropyl)benzimidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3-Aminopropyl)benzimidazole (CAS 42784-26-9), molecular formula C10H13N3 and molecular weight 175.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Aminopropyl)benzimidazole (C10H13N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2-(3-Aminopropyl)benzimidazole 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.
