Chemical Structure

4,4'-Bis(4-methyl-1H-imidazol-1-yl)-1,1'-biphenyl CAS 1789726-52-8 chemical structure

Description

Based on its molecular formula C20H18N4, 4,4'-Bis(4-methyl-1H-imidazol-1-yl)-1,1'-biphenyl contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4,4'-Bis(4-methyl-1H-imidazol-1-yl)-1,1'-biphenyl (CAS 1789726-52-8), molecular formula C20H18N4 and molecular weight 314.38 g/mol, is a CATO reference standard with documented purity and traceability.

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.
