Specification
Antimony(iii) sulfate (2:3) (CAS NO.7446-32-4) is high toxic. It is flammable. It will produce toxic sulfur oxide and antimony compounds smoke when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Antimony(iii) sulfate (2:3) (CAS NO.7446-32-4) separate from raw materials of food.
