Chemical Structure
Description
The occurrence of 4,4'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine (CAS 1839090-56-0), molecular formula C36H26N2 and molecular weight 486.61 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C36H26N2, 4,4'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 4,4'-((2,2-Diphenylethene-1,1-diyl)bis(4,1-phenylene))dipyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
