Solubility of 4-aco-mipt in water? Hi, my friend is attempting to prepair a solution for his rat and has found very low solubilty of said compound under 90 F distilled h2o, what gives? Does he need to use a etoh solution, or go for a higher ph? Will he have to weight out EVERY dose?! Peace, Mush PS. I had heard this stuff was hygroscopic, so didn't think h2o solutions would be a prob. This is a dry white crystaline powder procured from a reliable location.
