Chemical Structure

1,1,2,2-Tetrakis(4-(pyridin-3-yl)phenyl)ethene CAS 1287777-24-5 chemical structure

Description

1,1,2,2-Tetrakis(4-(pyridin-3-yl)phenyl)ethene (CAS 1287777-24-5), molecular formula C46H32N4 and molecular weight 640.77 g/mol, is a CATO reference standard with documented purity and traceability.

1,1,2,2-Tetrakis(4-(pyridin-3-yl)phenyl)ethene (C46H32N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 1,1,2,2-Tetrakis(4-(pyridin-3-yl)phenyl)ethene 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.
