5-(2-Methanesulfonylphenyl)-3-[4-(trifluoromethyl)phenyl]-1,2,4-oxadiazole CAS 339099-86-4

Description

5-(2-Methanesulfonylphenyl)-3-[4-(trifluoromethyl)phenyl]-1,2,4-oxadiazole (CAS 339099-86-4), molecular formula C16H11F3N2O3S and molecular weight 368.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 5-(2-Methanesulfonylphenyl)-3-[4-(trifluoromethyl)phenyl]-1,2,4-oxadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
