HEXAETHYL TETRAPHOSPHATE Chemical compatibility with O-rings, rubbers, & plastics

Hexaethyl tetraphosphate is an organophosphate compound with the molecular formula C8H21O7P4. It is a colorless to yellow liquid with a faint odor and is primarily used as an insecticide. Hexaethyl tetraphosphate functions by inhibiting acetylcholinesterase, an enzyme essential for nerve function in insects, leading to their paralysis and death. It has been used in agriculture to control a variety of pests on crops. However, due to its toxicity to humans and animals, its use has been significantly restricted or banned in many regions. Exposure to hexaethyl tetraphosphate can cause severe neurological effects, respiratory distress, and gastrointestinal symptoms. Proper handling, storage, and disposal are crucial to prevent accidental exposure and environmental contamination. The chemical's hazardous nature necessitates strict regulatory controls and the use of safer alternatives in pest management.
