I'm trying to dissolve some 90% GA3 in 99% isopropyl alcohol, but am not having much luck at it. I've been trying to dissolve the same 0.04 grams for the last 16 hours, adding more alcohol than I probably should have.
So far no amount of agitation is breaking it down(at least half of it is still undissolved), and I'm going to have to partially evaporate the alcohol to get it down to usable levels. Right now, I'm looking for other successful methods for dissolving GA3, but baking soda is rumoured to negate the GA3 and I have been unable to find clear ammonia anywhere today.
Does anyone have any suggestions?

Here's how I do it.
I take a test tube and put 1/32 (0,08 g) teaspoon GA3 90% in it then I add 0,25-0,50 ml of isopropyl alcohol 90%.
In another cup, I put boiling water then put the test tube in it and shake until the GA3 is completely dissolved (I do no let water reach in, this is just to raise alcohol temp...).
After that, I drop the dissolved GA3 in 237ml distilled water and shake well. It's probably better at this stage to not have cold dsitilled water in wich case the GA3 could recrystallize.
It give me approximately a 300 ppm solution.
That's it. For me it work everytime.

Hi Cole, you can dissolve it with one teaspoon of isopropyl alcohol.
Mix it in an empty small glass hot sauce or similar bottle with the lid screwed on tight and heat it in your microwave oven for 5 seconds.
It is important that the lid is sealed on tight and that the solution is only heated for 5 seconds.
Heat it for the five seconds and take it out and swirl it some more with the lid still tightened on the bottle.
You might have to heat it twice, but you should notice a big improvement doing it the first time.
No smoking or open flames allowed when doing this procedure.
Let us know how it works out for you.

Thanks for the advice, everyone! It's now almost fully dissolved, what I did was microwave some water to near boiling, took the little capped plastic vial I was using to mix the alcohol and GA3 and submerged it for a few seconds at a time, shaking in between dunks, added a couple more drops alcohol(still less than 5ml total), repeated the heating and shaking, and it is now just about ready to go! Thanks again!
