General description

Zinc diethyldithiocarbamate is an organometallic precursor used as an accelerator in the vulcanization of natural rubber latex films.

Application

Zinc diethyldithiocarbamate (Zn(S2CNEt2)2, ZDTC) can be used as an organocatalyst for the synthesis of high molecular weight polyurethanes from PEG- and PPG-diol macromonomers for use in biomedical applications. In comparison to other zinc catalysts, ZDTC demonstrated outstanding activity in the preparation of polyurethanes because of its tolerance to different organic solvents.
It can also be used as:
  • A catalyst for the polymerization of olefin oxides.
  • A precursor to prepare zinc sulfide semiconductor nanowires, which can be used as building blocks for photonic devices.
