Chemical Structure
Description
2-(Ethylthio)-1-(2-fluorophenyl)ethan-1-one (C10H11FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(Ethylthio)-1-(2-fluorophenyl)ethan-1-one (CAS 1157221-59-4) is a high-purity analytical reference standard with the molecular formula C10H11FOS and a molecular weight of 198.26 g/mol.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
