Chemical Structure
Description
The molecular framework of 5-Amino-4,5,6,7-tetrahydrobenzimidazole (C7H11N3) is characterized by a nitrile group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Amino-4,5,6,7-tetrahydrobenzimidazole (CAS 72748-85-7) is a high-purity analytical reference standard with the molecular formula C7H11N3 and a molecular weight of 137.18 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
