Crawley's classic FX 37 formula uses 0.5 g of Phenidone. It is far easier to measure out 50 ml of the 1% solution to use in a liter of FX 37 than trying to accurately weigh 0.5 g each time.
I've just been corrected by Bill Troop on this. Rather than trying to paraphrase what he said here is what he sent me in an email:
"If you really want to use phenidone, then you need to get a microgram scale (which is not that expensive anymore) and weigh out the tiny amounts you need. Yes, it's a pain, but it's the only certain way to make sure your phenidone will give you the activity you require. I will discuss in more detail some of the solutions that have been proposed, but I don't like any of them. These guys have this attitude: 'I want a phenidone percentage solution. Everyone says it's a problem. There ought to be a solution. I'm sure there's a solution.' Well, there isn't.
"It is deeply complicated by the fact that the reaction products of going-bad phenidone work so strongly with HQ, which in a sense revives the declining chemical. It's a mess.
"There's only one right way to work with phenidone. Buy it fresh, use it fresh.
"For the other chemicals you mention, water is an adequate solvent, though things like BZT can be tricky."
