Chemical Structure
Description
The occurrence of Ethyl 2-Fluoro-4-(methylsulfonyl)benzoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-Fluoro-4-(methylsulfonyl)benzoate (CAS 1354940-65-0), molecular formula C10H11FO4S and molecular weight 246.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11FO4S, Ethyl 2-Fluoro-4-(methylsulfonyl)benzoate contains a sulfone group, 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 246.26 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 2-Fluoro-4-(methylsulfonyl)benzoate 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.
