Chemical Structure

1-Ethyl-2-methyl-1H-benzo[d]imidazol-5-amine CAS 20982-18-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-2-methyl-1H-benzo[d]imidazol-5-amine.

CATO supplies 1-Ethyl-2-methyl-1H-benzo[d]imidazol-5-amine (CAS 20982-18-7), a certified reference material (molecular formula C10H13N3, MW 175.23 g/mol) for analytical method development and quality control.

1-Ethyl-2-methyl-1H-benzo[d]imidazol-5-amine (C10H13N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
