Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Phenethyl-1,3,4-oxadiazol-2(3H)-one.
5-Phenethyl-1,3,4-oxadiazol-2(3H)-one (CAS 34544-64-4) is a high-purity analytical reference standard with the molecular formula C13H12N4O2S and a molecular weight of 288.32 g/mol.
Structurally, 5-Phenethyl-1,3,4-oxadiazol-2(3H)-one (C13H12N4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 288.32 g/mol, it falls into the medium-molecular-weight range. 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.
