Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(5-(Trifluoromethyl)-1,2,4-oxadiazol-3-yl)aniline.
3-(5-(Trifluoromethyl)-1,2,4-oxadiazol-3-yl)aniline (CAS 71754-23-9) is a high-purity analytical reference standard with the molecular formula C9H6F3N3O and a molecular weight of 229.16 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(5-(Trifluoromethyl)-1,2,4-oxadiazol-3-yl)aniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.16 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.
