Chemical Structure
Description
4-(5-Amino-1-methyl-1H-benzoimidazol-2-yl)-butyric acid dihydrochloride (CAS 1185293-06-4) is a high-purity analytical reference standard with the molecular formula C12H15N3O2HCl and a molecular weight of 269.73 g/mol.
The molecular framework of 4-(5-Amino-1-methyl-1H-benzoimidazol-2-yl)-butyric acid dihydrochloride (C12H15N3O2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
