Chemical Structure

3-Amino-1,2,4-oxadiazole-5-carbonitrile CAS 2090134-95-3 chemical structure

Description

3-Amino-1,2,4-oxadiazole-5-carbonitrile (CAS 2090134-95-3), molecular formula C3H2N4O and molecular weight 110.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Amino-1,2,4-oxadiazole-5-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Amino-1,2,4-oxadiazole-5-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.
