Compared with other compounds in its class, the molecular weight of 526.71 g/mol gives (4S,4'S)-1,1'-Di([1,1'-biphenyl]-4-yl)-4,4'-diisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4S,4'S)-1,1'-Di([1,1'-biphenyl]-4-yl)-4,4'-diisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (CAS 2374958-86-6), molecular formula C36H38N4 and molecular weight 526.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4S,4'S)-1,1'-Di([1,1'-biphenyl]-4-yl)-4,4'-diisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (C36H38N4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
