Chemical Structure
Description
2-(3-Chlorophenyl)-1-(4-chlorophenyl)ethan-1-one (CAS 68968-12-7), molecular formula C14H10Cl2O and molecular weight 265.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 2-(3-Chlorophenyl)-1-(4-chlorophenyl)ethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 2-(3-Chlorophenyl)-1-(4-chlorophenyl)ethan-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.
