In accordance with the present invention, there are provided methods for producing pharmaceutical-grade dithiocarbamates and disulfide derivatives thereof. Invention methods are preferably conducted under sterile conditions, thereby producing a sterile pharmaceutical-grade disulfide derivative of a dithiocarbamate. In one embodiment, the invention method comprises vigorously contacting a mixture of carbon disulfide, at least one secondary amine, and a pharmaceutically acceptable diluent in a mixing zone under an inert gas atmosphere, wherein the diluent is a solvent for the carbon disulfide, but not for the dithiocarbamate. The invention method further comprises contracting the resulting reaction mixture with an oxidizing agent under conditions suitable to convert dithiocarbamate into the disulfide derivative thereof.
