Greetings, fellow travelers!
I apologize if I'm posting this in the wrong place, and I've scoured the archives here at BL in an attempt to avoid asking a totally redundant question, but I have yet to discover a satisfactory answer to the query I pose in my posts' title.
Specifically, I'm looking at the possibility of making a liquid solution out of AL-LAD and I'd like it to remain as stable as possible for longish-term storage--inasmuch as said solution CAN be stabilized. To this end I've been considering different solvents that might suffice, and it seems as though absolute ethanol (aka, 99.5% undenatured anhydrous ethanol USP) might work, but I'd really like to get some feedback from some of the more technically inclined and experienced voices here before I take the plunge.
Basically, my question is this: am I correct in thinking that an absolute ethanol solution of AL-LAD--kept in sealed glass vials in a freezer--will be significantly more stable than a similar solution using 95% ethanol (e.g., Everclear)?
If not, what solvent or approach would anyone recommend instead (besides obviously keeping the material as the dry tartarate salt)?
Or, am I just faced with the fact that NO solution (or solvent) will provide me with increased stability for a prospective solution of AL-LAD?
Thanks in advance for any and all feedback, and happy trails to everyone!
