Chemical Structure

(E)-4-(3-Bromophenyl)-1-(4-bromophenyl)but-3-en-1-one CAS 1321685-46-4 chemical structure

Description

Based on its molecular formula C16H12Br2O, (E)-4-(3-Bromophenyl)-1-(4-bromophenyl)but-3-en-1-one contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 380.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(E)-4-(3-Bromophenyl)-1-(4-bromophenyl)but-3-en-1-one (CAS 1321685-46-4) is a high-purity analytical reference standard with the molecular formula C16H12Br2O and a molecular weight of 380.07 g/mol.

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.
