I got crystals from an ethyl acetate fraction, but the problem is that the crystals do not dissolve in any solvent and I could not check its purity. How can I fix the problem?
Please give more detail about the origin
Do you know the chemical formula of the crystals? if yes you can chek in some places what are iits solvents.
