2-(3-Iodophenyl)-1-phenyl-1H-benzo[d]imidazole-5-carbonitrile CAS 919794-86-8

Description

The occurrence of 2-(3-Iodophenyl)-1-phenyl-1H-benzo[d]imidazole-5-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Iodophenyl)-1-phenyl-1H-benzo[d]imidazole-5-carbonitrile (CAS 919794-86-8), molecular formula C20H12IN3 and molecular weight 421.23 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3-Iodophenyl)-1-phenyl-1H-benzo[d]imidazole-5-carbonitrile (C20H12IN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
