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.
