Chemical Structure
Description
As a certified reference material (CRM), 3,3'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3,3'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine (CAS 2160539-20-6) is a high-purity analytical reference standard with the molecular formula C36H26N2 and a molecular weight of 486.61 g/mol.
Structurally, 3,3'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine (C36H26N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 486.61 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).
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.
