Chemical Structure

1-Phenyl-1H-benzo[d]imidazole-2,5-diamine CAS 832102-57-5 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-Phenyl-1H-benzo[d]imidazole-2,5-diamine.

1-Phenyl-1H-benzo[d]imidazole-2,5-diamine (CAS 832102-57-5) is a high-purity analytical reference standard with the molecular formula C13H12N4 and a molecular weight of 224.26 g/mol.

The molecular framework of 1-Phenyl-1H-benzo[d]imidazole-2,5-diamine (C13H12N4) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
