Compared with other compounds in its class, the molecular weight of 240.62 g/mol gives 2-Chloro-1-(5-(4-fluorophenyl)-1,3,4-oxadiazol-2-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-1-(5-(4-fluorophenyl)-1,3,4-oxadiazol-2-yl)ethan-1-one (CAS 929972-61-2) is a high-purity analytical reference standard with the molecular formula C10H6ClFN2O2 and a molecular weight of 240.62 g/mol.
Based on its molecular formula C10H6ClFN2O2, 2-Chloro-1-(5-(4-fluorophenyl)-1,3,4-oxadiazol-2-yl)ethan-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.62 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.
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.
