Chemical Structure
Description
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.
(2E)-1,3-Bis(4-fluorophenyl)prop-2-en-1-one (CAS 2805-56-3), molecular formula C15H10F2O and molecular weight 244.24 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-1,3-Bis(4-fluorophenyl)prop-2-en-1-one (C15H10F2O) contains a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (2E)-1,3-Bis(4-fluorophenyl)prop-2-en-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
