Heterophos Specification

 Heterophos (CAS NO.40626-35-5) is also called BRN 2122115 ; Heterofos ; O-Ethyl O-phenyl S-propyl phosphorothioate ; Phostil ; Phosphorothioic acid, O-ethyl O-phenyl S-propyl ester . Heterophos (CAS NO.40626-35-5) is high toxic. It is flammable. It will produce toxic phosphorus oxide and sulfur oxide fumes when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Heterophos (CAS NO.40626-35-5) separate from raw materials of food.
