Description

Compared with other compounds in its class, the molecular weight of 338.31 g/mol gives Dimethyl 4,4'-(1,3,4-oxadiazole-2,5-diyl)dibenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dimethyl 4,4'-(1,3,4-oxadiazole-2,5-diyl)dibenzoate (CAS 7531-07-9) is a high-purity analytical reference standard with the molecular formula C18H14N2O5 and a molecular weight of 338.31 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Dimethyl 4,4'-(1,3,4-oxadiazole-2,5-diyl)dibenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.31 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.
