 Sodium butylmercuric thioglycollate (CAS NO.64048-05-1) is also called Thioglycolic acid, S-(butylmercuric)-, sodium salt ; Mercurate(1-), butyl(mercaptoacetato(2-)-O,S-), sodium . Sodium butylmercuric thioglycollate (CAS NO.64048-05-1) is high toxic. It is flammable. It will produce mercury and sulfur oxides, sodium oxide smoke spicy boost when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Sodium butylmercuric thioglycollate (CAS NO.64048-05-1) separate from raw materials of food.
