Ethyl 4-fluoro-2-methoxybenzoate (CAS 167758-90-9) is a high-purity analytical reference standard with the molecular formula C10H11FO3 and a molecular weight of 198.19 g/mol.
Based on its molecular formula C10H11FO3, Ethyl 4-fluoro-2-methoxybenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures Ethyl 4-fluoro-2-methoxybenzoate 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.
