I have som concerta 36 mg tablets.

I want the methylphenidate pure.

In concerta its a lot of shiit (its depot) and its also methylphenidateHCL

merck didnt even list the HCL complex. I have looked around, but i dont find a shiit about solubility.

Any experts that can look at the structure and say what you think, I am not sure but ithe MFHCL is probably water soluble?

How do you recommend me to do to get it pure?

I just thought extract with water, basify, extraxt with organic solvent, and then add HCL. But its really alot of shiit, I want it reasonable pure.
