Chemical Structure

(E)-But-2-ene-2,3-diyldibenzene CAS 782-06-9 chemical structure

Description

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.

CATO supplies (E)-But-2-ene-2,3-diyldibenzene (CAS 782-06-9), a certified reference material (molecular formula C16H16, MW 208.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H16, (E)-But-2-ene-2,3-diyldibenzene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.30 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.
