(4R,5R)-4,5-diphenyl-4,5-dihydro-1H-imidazole CAS 1322804-32-9 chemical structure

Description

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.

(4R,5R)-4,5-diphenyl-4,5-dihydro-1H-imidazole (CAS 1322804-32-9), molecular formula C15H14N2 and molecular weight 222.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (4R,5R)-4,5-diphenyl-4,5-dihydro-1H-imidazole (C15H14N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 222.29 g/mol, it falls into the medium-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).

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.
