Chemical Structure
Description
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.
5-[(4-Methoxyphenoxy)methyl]-3-[3-(trifluoromethyl)phenyl]-1,2,4-oxadiazole (CAS 860784-37-8) is a high-purity analytical reference standard with the molecular formula C17H13F3N2O3 and a molecular weight of 350.29 g/mol.
The molecular framework of 5-[(4-Methoxyphenoxy)methyl]-3-[3-(trifluoromethyl)phenyl]-1,2,4-oxadiazole (C17H13F3N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
