5-(5-Amino-1H-benzo[d]imidazol-2-yl)benzene-1,3-diamine CAS 351226-56-7

Description

The occurrence of 5-(5-Amino-1H-benzo[d]imidazol-2-yl)benzene-1,3-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(5-Amino-1H-benzo[d]imidazol-2-yl)benzene-1,3-diamine (CAS 351226-56-7), molecular formula C13H13N5 and molecular weight 239.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-(5-Amino-1H-benzo[d]imidazol-2-yl)benzene-1,3-diamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.28 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), 5-(5-Amino-1H-benzo[d]imidazol-2-yl)benzene-1,3-diamine 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.
