.alpha.-Oxopropionitrile 2-Oxopropionitrile 631-57-2 ACETYL CYANIDE NSC-91482 NSC91482 Oxopropionitrile Oxypropionitrile Propanenitrile, 2-oxo- Pyruvic acid nitrile Pyruvonitrile (CAS 631-57-2), molecular formula C3H3NO and molecular weight 69.06 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, .alpha.-Oxopropionitrile 2-Oxopropionitrile 631-57-2 ACETYL CYANIDE NSC-91482 NSC91482 Oxopropionitrile Oxypropionitrile Propanenitrile, 2-oxo- Pyruvic acid nitrile Pyruvonitrile (C3H3NO) 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 69.06 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), .alpha.-Oxopropionitrile 2-Oxopropionitrile 631-57-2 ACETYL CYANIDE NSC-91482 NSC91482 Oxopropionitrile Oxypropionitrile Propanenitrile, 2-oxo- Pyruvic acid nitrile Pyruvonitrile 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.
