Chemical Structure
Description
CATO supplies 1,3-Bis(4-chlorophenyl)-2-propen-1-one (CAS 19672-59-4), a certified reference material (molecular formula C15H10Cl2O, MW 277.15 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H10Cl2O, 1,3-Bis(4-chlorophenyl)-2-propen-1-one contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
