Dimethyl sulfoxide (DMSO), a by-product of the wood industry, has been in use as a commercial solvent since 1953. It is also one of the most studied but least understood pharmaceutical agents of our time--at least in the United States.
Deuterated DMSO is produced by heating DMSO in heavy water (D2O) with a basic catalyst such as calcium oxide. The reaction does not give complete conversion to the d6 product, and the water produced must be removed and replaced with D2O several times to drive the equilibrium to the fully deuterated product.
