Chemical Structure
Description
Structurally, 4,4',5,5'-Tetrahydro-1H,1'H-2,2'-biimidazole (C6H10N4) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 138.17 g/mol, it falls into the low-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).
CATO supplies 4,4',5,5'-Tetrahydro-1H,1'H-2,2'-biimidazole (CAS 934-03-2), a certified reference material (molecular formula C6H10N4, MW 138.17 g/mol) for analytical method development and quality control.
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.
