Chemical Structure
Description
The molecular framework of 1-(4-Chlorophenyl)-3-(2,4-dichlorophenyl)prop-2-en-1-one (C15H9Cl3O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(4-Chlorophenyl)-3-(2,4-dichlorophenyl)prop-2-en-1-one (CAS 57076-84-3), molecular formula C15H9Cl3O and molecular weight 311.59 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(4-Chlorophenyl)-3-(2,4-dichlorophenyl)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.
