Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4'-(3,5-Bis(pyridin-4-ylethynyl)phenyl)-2,2':6',2''-terpyridine.
4'-(3,5-Bis(pyridin-4-ylethynyl)phenyl)-2,2':6',2''-terpyridine (CAS 1478039-72-3) is a high-purity analytical reference standard with the molecular formula C35H21N5 and a molecular weight of 511.57 g/mol.
Structurally, 4'-(3,5-Bis(pyridin-4-ylethynyl)phenyl)-2,2':6',2''-terpyridine (C35H21N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 511.57 g/mol, it falls into the moderately-high-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).
