Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 640.77 g/mol gives 1,1,2,2-Tetrakis(4-(pyridin-4-yl)phenyl)ethene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,1,2,2-Tetrakis(4-(pyridin-4-yl)phenyl)ethene (CAS 1227195-24-5), a certified reference material (molecular formula C46H32N4, MW 640.77 g/mol) for analytical method development and quality control.
The molecular framework of 1,1,2,2-Tetrakis(4-(pyridin-4-yl)phenyl)ethene (C46H32N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
