Chemical Structure

(4S,4'S)-4,4'-Di((S)-sec-butyl)-1,1'-bis(3,5-di-tert-butylphenyl)-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole CAS 2697181-90-9 chemical structure

Description

The occurrence of (4S,4'S)-4,4'-Di((S)-sec-butyl)-1,1'-bis(3,5-di-tert-butylphenyl)-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (4S,4'S)-4,4'-Di((S)-sec-butyl)-1,1'-bis(3,5-di-tert-butylphenyl)-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (CAS 2697181-90-9), a certified reference material (molecular formula C42H66N4, MW 627.00 g/mol) for analytical method development and quality control.

Structurally, (4S,4'S)-4,4'-Di((S)-sec-butyl)-1,1'-bis(3,5-di-tert-butylphenyl)-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (C42H66N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 627.00 g/mol, it falls into the high-molecular-weight range. 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).

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.
