I need a plan B...

Caroline is correct. DMF is an industrial chemical used to make paints and glues among other things. Any patent would be long expired. I tried to get some from a US company but I was refused. No problem getting it from China, but it is a restricted drug in Australia since Tecfidera was approved, although you can get an exemption for non-therapeutic commercial use. Can be made with fumaric and sulphuric acids and methanol (all legal).

Cheers,

Bill
