Chemical Structure
Description
The molecular framework of 4-Chloro-3-(5-chloro-1-methyl-1H-benzo[d]imidazol-2-yl)aniline (C14H11Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-Chloro-3-(5-chloro-1-methyl-1H-benzo[d]imidazol-2-yl)aniline (CAS 423755-06-0) is a high-purity analytical reference standard with the molecular formula C14H11Cl2N3 and a molecular weight of 292.16 g/mol.
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.
