Structurally, 4-([2,2’:6’,2’’-Terpyridin]-4’-yl)aniline (C21H16N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 324.38 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-([2,2’:6’,2’’-Terpyridin]-4’-yl)aniline (CAS 178265-65-1) is a high-purity analytical reference standard with the molecular formula C21H16N4 and a molecular weight of 324.38 g/mol.
