Chemical Structure

2-Methyl-1H-benzimidazole-1-ethanamine CAS 61981-79-1 chemical structure

Description

2-Methyl-1H-benzimidazole-1-ethanamine (CAS 61981-79-1), 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-Methyl-1H-benzimidazole-1-ethanamine (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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
