Description

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

227 g in steel cylinder

Other Notes

For 295590-270G-EU packaging: 400 mL of aluminium cylinder equipped with brass valve.

Recommended products
