3-(3-Ethyl-1,2,4-oxadiazol-5-yl)pyridin-2-amine CAS 1774902-62-3

Description

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

3-(3-Ethyl-1,2,4-oxadiazol-5-yl)pyridin-2-amine (CAS 1774902-62-3), molecular formula C9H10N4O and molecular weight 190.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H10N4O, 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)pyridin-2-amine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 190.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)pyridin-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.
