Chemical Structure
Description
4,4'-(1,3-Dimethyl-2,3-dihydro-1H-imidazole-4,5-diyl)dipyridine (CAS 6628-96-2) is a high-purity analytical reference standard with the molecular formula C15H16N4 and a molecular weight of 252.31 g/mol.
Structurally, 4,4'-(1,3-Dimethyl-2,3-dihydro-1H-imidazole-4,5-diyl)dipyridine (C15H16N4) 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 252.31 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).
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.
