Storage method


Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, etc. and avoid mixed storage. Equipped with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with leakage emergency treatment equipment
Prepare and appropriate containment materials.


Synthesis method

Available by Diazoserine is extracted from the fermentation broth of actinomycetes and can also be synthesized by chemical methods.

Purpose

For transplantation of bacteria, molds, and animals and plants It has inhibitory effect on tumors. It is mainly used to treat acute leukemia and certain tumors and can be taken orally.
