Chemical Structure

5-Amino-1,3,4-oxadiazole-2-carbonitrile CAS 134318-57-3 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.

5-Amino-1,3,4-oxadiazole-2-carbonitrile (CAS 134318-57-3), molecular formula C3H2N4O and molecular weight 110.07 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Amino-1,3,4-oxadiazole-2-carbonitrile (C3H2N4O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 110.07 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-Amino-1,3,4-oxadiazole-2-carbonitrile 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.
