Application

  • Nitrous oxide allows selective oxygen atom transfer reactions while minimizing the risk of over-oxidation. Therefore, it is used to oxidize disilenes, silanimines, silaethenes and silylenes.
  • Along with Ru-porphyrin catalyst, it can be used in the epoxidation of olefins and steroids.
  • It can be used as an oxidant in for the metal-catalyzed oxidative homo- and cross-coupling of Grignard reagents.
  • N2O can also be used as a nitrogen-dopant source to synthesize p-type zinc oxide nanowires (ZnO NWs) via vapor-liquid-solid growth.

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.
