(4S,4'S)-4,4'-Diisopropyl-1,1'-di-m-tolyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole CAS 2374958-85-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4S,4'S)-4,4'-Diisopropyl-1,1'-di-m-tolyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole.

(4S,4'S)-4,4'-Diisopropyl-1,1'-di-m-tolyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (CAS 2374958-85-5), molecular formula C26H34N4 and molecular weight 402.57 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C26H34N4, (4S,4'S)-4,4'-Diisopropyl-1,1'-di-m-tolyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 402.57 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).

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.
