Finally......a thread on long-term storage. I've had the following info posted in the Mega thread without any very expert-level type replies. I know you aren't supposed to cross-post, but I really would like to participate in a focused discussion on this topic. Also, I've done a bunch of internet research, and hopefully someone here will benefit from what I've found. My specific interests are in JWH-018 and JWH-073.
I have searched all over the net, and I've found the following snippets (I appologize in advance for the plagerism).
“Indole compounds degrade by oxidation giving yellow and brown products. The more impurity results in intensity of the brown color and becoming a gummy like state (due to melting point suppression)”
"With all synthetic compounds, storage at temps below -20C limits molecular interaction....resulting in less degradation over time. Hence, if you want to keep it for more than a week or so, store it in the freezer in an airtight container with little shoe silicon packs to absorb water."
From a supplier in a methyl acetate solution: "For long term storage, we suggest it be stored as supplied at -20C (-4F). It should be stable for at least one year" I am not sure how much this one applies since everything normally available for purchase from most places is in powder form.
"Eventually you have a perfectly dissolved JWH solution (in Everclear) which can be stored in the freezer or fridge, in a liquor bottle or, even better, a white wine bottle with a screwcap (no cork!) works great. It will store indefinitely."
And the ubiquous: "I've kept mine in a plastic bag in my closet for 3 months and it was OK"
Like the original poster to this thread, what I am is looking for is a way to maximize storage for a long term - like decades, if possible. Considering the stuff quoted above I have postulated two theories, but really need a chemist type to chime in and help us all understand synthetic cannibanoid breakdown at the molecular level. (I am not a chemist, in any way)
Theory 1: Since Oxidation is the enemy of JWH-018, then storage in lots of little small glass vials (with no empty space between the powder and the cap/stopper to mimimize exposure to air) in your everyday stand-alone freezer would work. You would pull out individual vials when you need them, leaving the others undisturbed.
Theory 2: By melting the JWH in Ethanol, you eliminate its ability to oxidize because no air can get to the chemical once it is in liquid form. Putting the ethanol in the freezer is an added bonus that retards chemical processes.
I would love to know which of the above statements might be true (if either) and/or anyone's thoughts on the best way to maintain the potency over very long time spans (10-15 years)
