Chemical Structure

N1,N1'-(1,4-Phenylenebis(methanylylidene))bis(N4-phenylbenzene-1,4-diamine) CAS 57400-99-4 chemical structure

Description

Structurally, N1,N1'-(1,4-Phenylenebis(methanylylidene))bis(N4-phenylbenzene-1,4-diamine) (C32H26N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 466.58 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).

N1,N1'-(1,4-Phenylenebis(methanylylidene))bis(N4-phenylbenzene-1,4-diamine) (CAS 57400-99-4), molecular formula C32H26N4 and molecular weight 466.58 g/mol, is a CATO reference standard with documented purity and traceability.
