Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2-Bis(2,4-dichlorophenyl)ethane-1,2-dione (CAS 54696-56-9), molecular formula C14H6Cl4O2 and molecular weight 348.01 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H6Cl4O2, 1,2-Bis(2,4-dichlorophenyl)ethane-1,2-dione contains a carboxylic acid group, 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 348.01 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.
As a certified reference material (CRM), 1,2-Bis(2,4-dichlorophenyl)ethane-1,2-dione 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.
