FAQ
Frequently Asked Questions
Historically, it was used as a potent insecticide and acaricide. Its current use is very limited due to high toxicity, but it remains an important compound in scientific research and toxicology.
Yes, it is highly toxic to humans through ingestion, inhalation, or skin absorption. It is a potent neurotoxin that inhibits cholinesterase, leading to potentially fatal nervous system effects.
The prefix 'tetra-' means four, and 'ethyl' refers to the -C2H5 chemical group. Therefore, 'tetraethyl' indicates the presence of four ethyl groups attached to the central molecular structure.
The standard abbreviation in scientific literature is TEPP.
A synthetic organophosphate compound used primarily as a potent insecticide and acaricide.
