Chemical Structure

1-Ethyl-4-nitro-1H-benzo[d]imidazole CAS 31419-70-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 191.19 g/mol gives 1-Ethyl-4-nitro-1H-benzo[d]imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Ethyl-4-nitro-1H-benzo[d]imidazole (CAS 31419-70-2) is a high-purity analytical reference standard with the molecular formula C9H9N3O2 and a molecular weight of 191.19 g/mol.

The molecular framework of 1-Ethyl-4-nitro-1H-benzo[d]imidazole (C9H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
