Compared with other compounds in its class, the molecular weight of 253.28 g/mol gives 5-[4-(Ethylsulfonyl)phenyl]-1,3,4-oxadiazol-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-[4-(Ethylsulfonyl)phenyl]-1,3,4-oxadiazol-2-amine (CAS 1177348-10-5), a certified reference material (molecular formula C10H11N3O3S, MW 253.28 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-[4-(Ethylsulfonyl)phenyl]-1,3,4-oxadiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.28 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5-[4-(Ethylsulfonyl)phenyl]-1,3,4-oxadiazol-2-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
