Ethyl 2-(2-fluoro-4-methylphenyl)-2-oxoacetate CAS 873547-99-0

Description

Ethyl 2-(2-fluoro-4-methylphenyl)-2-oxoacetate (C11H11FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Ethyl 2-(2-fluoro-4-methylphenyl)-2-oxoacetate (CAS 873547-99-0) is a high-purity analytical reference standard with the molecular formula C11H11FO3 and a molecular weight of 210.20 g/mol.

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.
