Specification
Selenium monochloride (CAS NO.10025-68-0) is also called Diselenium dichloride ; Selenium chloride . Selenium monochloride (CAS NO.10025-68-0) is high toxic. It is not flammable. It will produce highly toxic hydrogen selenide gas by heat and water. So the storage environment should be ventilate, low-temperature and dry. Keep Selenium monochloride (CAS NO.10025-68-0) separate from raw materials of food and acid.
