Chemical Structure

(5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine CAS 889939-69-9 chemical structure

Description

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.

CATO supplies (5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine (CAS 889939-69-9), a certified reference material (molecular formula C5H9N3O, MW 127.14 g/mol) for analytical method development and quality control.

Structurally, (5-Ethyl-1,2,4-oxadiazol-3-yl)methanamine (C5H9N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 127.14 g/mol, it falls into the low-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).

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