Chemical Structure
Description
CATO supplies Methyl 2-(4-fluoro-2-methylphenyl)-2-oxoacetate (CAS 334477-07-5), a certified reference material (molecular formula C10H9FO3, MW 196.18 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 2-(4-fluoro-2-methylphenyl)-2-oxoacetate (C10H9FO3) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 2-(4-fluoro-2-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.
