Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger pests such as possum.ompound 1 is the starting ester needed to synthesize brodifacoum. To obtain this starting compound a simple Wittig condensation of ethyl chloroacetate with 4â-bromobiphenylcarboxaldehyde was accomplished.
Cesium iodide is a material with a high g-ray stopping power due to its relative high density and Z value. For scintillation counting, it is used either in its undoped form or doped with sodium or thallium. Cesium iodide is noted for its high resistance to thermal and mechanical shock due to the absence of a cleavage plane. Most physical characteristics of CsI are independent of the activator used.
