Phenidone keeps just fine, both in the powder form and in stock solutions where the powder is mixed either with isopropyl alcohol (at least 90%) or propylene glycol. It will keep indefinitely. My little jar of Phenidone powder that I use to mix the stock solutions has been around since Noah came off the ark, and it's still potent.
