Chemical Structure
Description
1-[3-(4-chlorophenoxy)phenyl]ethan-1-one (CAS 56911-59-2) is a high-purity analytical reference standard with the molecular formula C14H11ClO2 and a molecular weight of 246.69 g/mol.
1-[3-(4-chlorophenoxy)phenyl]ethan-1-one (C14H11ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-[3-(4-chlorophenoxy)phenyl]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.
