Chemical Structure
Description
(4S,4'S,5S,5'S)-2,2'-(1,3-Phenylene)bis[4,5-dihydro-4,5-diphenyl-1H-imidazole] (CAS 1208333-06-5), molecular formula C36H30N4 and molecular weight 518.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C36H30N4, (4S,4'S,5S,5'S)-2,2'-(1,3-Phenylene)bis[4,5-dihydro-4,5-diphenyl-1H-imidazole] contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 518.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
