Ethyl 2-(3,5-dichlorophenyl)-2-oxoacetate (CAS 845790-52-5) is a high-purity analytical reference standard with the molecular formula C10H8Cl2O3 and a molecular weight of 247.07 g/mol.
The molecular framework of Ethyl 2-(3,5-dichlorophenyl)-2-oxoacetate (C10H8Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
