General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Catalyst for hydrogenation of various functional groups with minimal hydrogenolysis problems; used as dehydrogenation catalyst; used for selective oxidation of primary alcohols.
Catalyst for:
  • Hydrohydrazination reactions
  • Oxidation of sugars
  • Low-temperature oxidation of carbon monoxide
  • Oxygen reduction reaction
  • Hydrogenation reactions
  • Hydrogenolysis of the cyclopropyl group into an isopropyl group
  • Hydroxycyclopropanation reactions
Platinum(IV) oxide has been used for the reduction of citernyl bromide to form (S)-3,7-dimethyloctylbromide.

For small scale and high throughput uses, product is also available as ChemBeads (928291)
