Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(2,3-Dimethylphenyl)-2-((5-(4-fluorophenyl)-1,3,4-oxadiazol-2-yl)thio)acetamide (CAS 334497-46-0), molecular formula C18H16FN3O2S and molecular weight 357.40 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H16FN3O2S, N-(2,3-Dimethylphenyl)-2-((5-(4-fluorophenyl)-1,3,4-oxadiazol-2-yl)thio)acetamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 357.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
