Specification:

 Tetra-n-propyl dithiopyrophosphate (CAS NO.3244-90-4) is also called 4-01-00-01432 (Beilstein Handbook Reference) ;
Aspon ; BRN 1715467 ; Bis(O,O-di(N-propyl))phosphorothionic anhydride ; Bis-O,O-di-n-propylphosphorothionic anhydride ; Caswell No. 845A ; EPA Pesticide Chemical Code 079101 ; HSDB 1776 ; O,O,O,O-Tetra-n-propyl dithiopyrophosphate ; O,O,O,O-Tetrapropyl dithiopyrophosphate ; Propyl thiopyrophosphate ; Propyl thiopyrophosphate (((PrO)2P(S))2O) ; Tetrapropyl dithiopyrophosphate ; Tetrapropyl thiodiphosphate ; Tetrapropyl thiopyrophosphate (8CI) ; Tetrapropyldithiodifosfat [Czech] ; Thiodiphosphoric acid (((HO)2P(S))2O), tetrapropyl ester ; Thiodiphosphoric acid tetrapropyl ester (9CI) ; Thiopyrophosphoric acid (((HO)2PS)2O), tetrapropyl ester ; Thiopyrophosphoric acid, tetrapropyl ester . Tetra-n-propyl dithiopyrophosphate (CAS NO.3244-90-4) is high toxic. It will produce toxic phosphorus oxides and sulfur oxide gases when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Tetra-n-propyl dithiopyrophosphate (CAS NO.3244-90-4) separate from raw materials of food.
