Chemical Structure
Description
(4S,4'S)-1,1',4,4'-Tetraisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (CAS 2374958-87-7), molecular formula C18H34N4 and molecular weight 306.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4S,4'S)-1,1',4,4'-Tetraisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole (C18H34N4) 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.
As a certified reference material (CRM), (4S,4'S)-1,1',4,4'-Tetraisopropyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
