Description

Compared with other compounds in its class, the molecular weight of 386.47 g/mol gives 1,3-Diphenyl-1-(3-(phenylamino)-1,2,4-thiadiazol-5-yl)guanidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3-Diphenyl-1-(3-(phenylamino)-1,2,4-thiadiazol-5-yl)guanidine (CAS 59236-39-4), molecular formula C21H18N6S and molecular weight 386.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1,3-Diphenyl-1-(3-(phenylamino)-1,2,4-thiadiazol-5-yl)guanidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.47 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.
