Chemical Structure
Description
Ethyl 3-fluoro-5-methylbenzoylformate (CAS 951888-58-7) is a high-purity analytical reference standard with the molecular formula C11H11FO3 and a molecular weight of 210.20 g/mol.
Based on its molecular formula C11H11FO3, Ethyl 3-fluoro-5-methylbenzoylformate 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 210.20 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 3-fluoro-5-methylbenzoylformate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
