Chemical Structure

5-(Thiophen-2-yl)-1,2,4-oxadiazol-3-amine CAS 73631-19-3 chemical structure

Description

5-(Thiophen-2-yl)-1,2,4-oxadiazol-3-amine (CAS 73631-19-3) is a high-purity analytical reference standard with the molecular formula C6H5N3OS and a molecular weight of 167.19 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 5-(Thiophen-2-yl)-1,2,4-oxadiazol-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.19 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.
