2-(4-Methoxyphenyl)-5-phenyl-1,3,4-oxadiazole CAS 842-79-5

Description

Compared with other compounds in its class, the molecular weight of 429.42 g/mol gives 2-(4-Methoxyphenyl)-5-phenyl-1,3,4-oxadiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Methoxyphenyl)-5-phenyl-1,3,4-oxadiazole (CAS 842-79-5) is a high-purity analytical reference standard with the molecular formula C21H23N3O7 and a molecular weight of 429.42 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-(4-Methoxyphenyl)-5-phenyl-1,3,4-oxadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 429.42 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
