Description

Compared with other compounds in its class, the molecular weight of 189.21 g/mol gives 4-(3-Ethyl-1,2,4-oxadiazol-5-yl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3-Ethyl-1,2,4-oxadiazol-5-yl)aniline (CAS 1015846-75-9), molecular formula C10H11N3O and molecular weight 189.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(3-Ethyl-1,2,4-oxadiazol-5-yl)aniline (C10H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 4-(3-Ethyl-1,2,4-oxadiazol-5-yl)aniline 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.
