Chemical Structure

4,4＇-Bis(2-methoxystyryl)biphenyl CAS 40470-68-6 chemical structure

Description

CATO supplies 4,4＇-Bis(2-methoxystyryl)biphenyl (CAS 40470-68-6), a certified reference material (molecular formula C30H26O2, MW 418.53 g/mol) for analytical method development and quality control.

Based on its molecular formula C30H26O2, 4,4＇-Bis(2-methoxystyryl)biphenyl contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
