Properties and stability
Use and store according to specifications, no decomposition will occur, and avoid contact with oxides
Storage method
Stored at 2-8°C in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
Synthesis method
It is prepared by heating carbon tetrachloride and carbon disulfide in the presence of aluminum triiodide (AlI3); it can also be prepared by reacting iodoform with potassium hypoiodite.
Purpose
for organic synthesis
