Acetaldoxime is used as an oxygen scavenger in boiler water. It is also used as an intermediate in chemical synthesis and pharmaceuticals. It is involved in the rearrangement reaction to prepare acetamide by using nickel(II) acetate as a catalyst. It acts as a precursor to prepare heterocyclic compound such as spiroisoxazoline. Further, it is used to prepare alkylated(Z)-oximes by deprotonation followed by reaction with benzyl bromide.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

  2. Chlorination with NCS: Tetrahedron, 40, 2985 (1984), or chlorine, gives the chloroxime, dehydrochlorination of which generates acetonitrile N-oxide, a reactive 1,3-dipole which undergoes cycloadditions with alkenes providing a one-pot route to 2-isoxazolines (same ref.):
  3. Nitrile oxides can be generated from other aldoximes in a similar manner. The resulting isoxazolines can readily be reduced to 3-hydroxy ketones.
