CATO supplies 1-(4-Bromobutoxy)-4-{1,2,2-tris[4-(4-bromobutoxy)phenyl]ethenyl}benzene (CAS 1204389-23-0), a certified reference material (molecular formula C42H48Br4O4, MW 936.44 g/mol) for analytical method development and quality control.
Based on its molecular formula C42H48Br4O4, 1-(4-Bromobutoxy)-4-{1,2,2-tris[4-(4-bromobutoxy)phenyl]ethenyl}benzene contains a carboxylic acid group, 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 936.44 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.
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.
