Chemical Structure

2-(1,2-Oxazol-3-yl)acetonitrile CAS 55242-83-6 chemical structure

Description

2-(1,2-Oxazol-3-yl)acetonitrile (CAS 55242-83-6) is a high-purity analytical reference standard with the molecular formula C5H4N2O and a molecular weight of 108.10 g/mol.

Structurally, 2-(1,2-Oxazol-3-yl)acetonitrile (C5H4N2O) 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 108.10 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).

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), 2-(1,2-Oxazol-3-yl)acetonitrile 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.
