CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Tetraethyl dithiopyrophosphate is an organic phosphate pesticide which acts as an inhibitor of cholinesterase, and as such it is highly toxic by all routes of exposure. It is a colorless to pale yellow mobile oil with an odor of garlic. It may be found as a liquid or as a dry mixture where the liquid is absorbed onto a dry carrier. |
