2,4-Dimethyl-7-nitro-1H-benzo[d]imidazole CAS 23291-70-5

Description

The occurrence of 2,4-Dimethyl-7-nitro-1H-benzo[d]imidazole is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Dimethyl-7-nitro-1H-benzo[d]imidazole (CAS 23291-70-5), molecular formula C9H9N3O2 and molecular weight 191.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2,4-Dimethyl-7-nitro-1H-benzo[d]imidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2,4-Dimethyl-7-nitro-1H-benzo[d]imidazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
