Storage method
This product should be sealed and stored in a cool and dry place.
Synthesis method
Produced by the addition of ethanolamine and hydrogen bromideβ-Ethylamine bromide, then It is cyclized with carbon disulfide in the presence of sulfuric acid and finally hydrolyzed. The reaction of this method is easy to control, does not require high equipment, and is suitable for industrial use. In addition, it can also be obtained by adding cycloethylamine and hydrogen sulfide.
Purpose
Treatment and protection of radiation sickness. Complexing agent and masking agent for metal ions such as nickel and copper. Organic Synthesis.
