Description

Compared with other compounds in its class, the molecular weight of 396.40 g/mol gives 4,4'-(5,5'-(1,4-Phenylene)bis(1,3,4-oxadiazole-5,2-diyl))dianiline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4'-(5,5'-(1,4-Phenylene)bis(1,3,4-oxadiazole-5,2-diyl))dianiline (CAS 22915-83-9), molecular formula C22H16N6O2 and molecular weight 396.40 g/mol, is a CATO reference standard with documented purity and traceability.

4,4'-(5,5'-(1,4-Phenylene)bis(1,3,4-oxadiazole-5,2-diyl))dianiline (C22H16N6O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
