Cleaning Etizolam powder

[alchemicalsamaritan]

Hello all! This is my first post have been a long time lurker here (since I was a dumb teenager) and have a question that I can't seem to find an answer to anywhere. Anyways I recently acquired some etizolam powder it didnt look particularly pure (almost yellow) but I've heard that's not neccesarily uncommon with benzo powders. I made a small solution 2mg/ml 30mgs in 15ml of pg and everything dissolved fine but when I went to try it for the first time it reeked of cat piss. At first I thought maybe my bottle was dirty or something but then upon smelling the powder itself realized that's the culprit for the smell. I was wondering if anyone had any idea on what would be a good solvent to use for cleaning the powder something like acetone? Or given benzos tricky solubility is there a better option?
