In which solvents is Product 206032, Platinum (IV) oxide, soluble?
Per the Merck Index, 13th Edition, when freshly precipitated, Platinum(IV) Oxide is soluble in concentrated acids and dilute phosphoric acid, especially when warmed.  It is easily soluble in dilute solutions of potassium hydroxide. 
Is Product 206032, Platinum (IV) oxide, water soluble?
It is insoluble in water.
How can Product 206032, Platinum (IV) oxide, be used as a catalyst?
Platinum(IV) oxide can be used as a catalyst in hydrogenations.  The actual catalyst is platinum black which is formed in situ by reduction of the PtO2 by the hydrogen used for the hydrogenation.  It is especially useful for reduction at room temperature and hydrogen pressures up to 4 atmospheres.  It is suitable for the reduction of double and triple bonds, aromatic nuclei, carbonyl groups, nitro groups, and nitriles.
Are there any safety concerns with Product 206032, Platinum (IV) oxide?
After exposure to hydrogen, the resulting platinum black can be pyrophoric.  Therefore, it should not be allowed to dry and all exposure to oxygen should be minimized.
Can the Platinum be recovered from Product 206032, Platinum (IV) oxide?
Internet sources do indicate that Platinum can be recovered from spent catalyst by conversion to ammonium chloroplatinate using aqua regia followed by ammonia.  However, we do have a process for doing so.
How do I find price and availability?
There are several ways to find pricing and availability for our products.  Once you log onto our website, you will find the price and availability displayed on the product detail page.
