Storage method
This product should be sealed and stored at 0℃ to avoid light. It can gradually decompose after long-term storage, and may cause an explosion when it decomposes to a certain pressure. Commercially available products often contain 50% water-wetting products.
Synthesis method
None
Purpose
Chemical mutagens and cancer research.
