5-(3-Chlorophenyl)-1,3,4-oxadiazol-2(3H)-one CAS 85929-41-5

Description

The occurrence of 5-(3-Chlorophenyl)-1,3,4-oxadiazol-2(3H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(3-Chlorophenyl)-1,3,4-oxadiazol-2(3H)-one (CAS 85929-41-5) is a high-purity analytical reference standard with the molecular formula C8H5ClN2O2 and a molecular weight of 196.59 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(3-Chlorophenyl)-1,3,4-oxadiazol-2(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
