Chemical Structure
Description
CATO supplies Ethyl 2-(4-fluoro-3-methylphenyl)-2-oxoacetate (CAS 732251-71-7), a certified reference material (molecular formula C11H11FO3, MW 210.20 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-(4-fluoro-3-methylphenyl)-2-oxoacetate (C11H11FO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Ethyl 2-(4-fluoro-3-methylphenyl)-2-oxoacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
