4,4'-Bis [2-(3-methoxyphenyl)ethenyl]-2,2'-bipyridine CAS 349545-75-1

Description

Compared with other compounds in its class, the molecular weight of 420.50 g/mol gives 4,4'-Bis [2-(3-methoxyphenyl)ethenyl]-2,2'-bipyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4,4'-Bis [2-(3-methoxyphenyl)ethenyl]-2,2'-bipyridine (CAS 349545-75-1), a certified reference material (molecular formula C28H24N2O2, MW 420.50 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4,4'-Bis [2-(3-methoxyphenyl)ethenyl]-2,2'-bipyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
