3-(((4-Chlorophenyl)sulfonyl)methyl)-5-(trifluoromethyl)-1,2,4-oxadiazole CAS 1024253-22-2

Description

3-(((4-Chlorophenyl)sulfonyl)methyl)-5-(trifluoromethyl)-1,2,4-oxadiazole (C10H6ClF3N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

3-(((4-Chlorophenyl)sulfonyl)methyl)-5-(trifluoromethyl)-1,2,4-oxadiazole (CAS 1024253-22-2) is a high-purity analytical reference standard with the molecular formula C10H6ClF3N2O3S and a molecular weight of 326.68 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.
