Meaning and Definition

A synthetic organophosphate compound used primarily as a potent insecticide and acaricide.

A chemical agent (C8H20O7P2) that functions as a cholinesterase inhibitor, disrupting nerve function in insects. Historically, it was investigated for potential medical uses (e.g., treatment of glaucoma) but is now almost exclusively a technical term in chemistry, toxicology, and pest control.

Dialectal Variation

British vs American Usage

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.

Tetraethyl pyrophosphate is usually technical/scientific in register.

Tetraethyl pyrophosphate: in British English it is pronounced /ˌtɛtrəˌiːθaɪl ˌpaɪrə(ʊ)ˈfɒsfeɪt/, and in American English it is pronounced /ˌtɛtrəˌɛθəl ˌpaɪroʊˈfɑːsfeɪt/. Tap the audio buttons above to hear it.
