Tebufenpyrad Usage And Synthesis

Chemical Properties

Tan Solid

Uses

Tebufenpyrad is a pyrazole acaricide and insecticide commonly used in commercial greenhouses.

Uses

Acaricide.

Definition

ChEBI: Tebufenpyrad is a pyrazole acaricide and a pyrazole insecticide. It has a role as a mitochondrial NADH:ubiquinone reductase inhibitor.

Metabolic pathway

By incubation of tebufenpyrad with rat liver homogenate, tebufenpyrad undergoes biotransformation to yield the major metabolites N-(4- tert-butylbenzyl)-4-chloro-3-(1-hydroxyethyl)-1- methylpyrazole-5-carboxamide via hydroxylation of the w-1-carbon of the ethyl group and N-[4-(1-carboxy-1- methylethyl)benzyl]-4-chloro-3-ethyl-1-methylpyrazole- 5-carboxamide via oxidation of the methyl group in the tert-butyl moiety to the carboxylic acid derivatives.
When the rat is orally dosed tebufenpyrad, the major metabolism pathway is via both hydroxylation and oxidation reactions to yield N-[4-(1-carboxy-1- methylethyl)benzyl]-4-chloro-3-(1-hydroxyethyl)-1- methylpyrazole-5-carboxamide which is mainly excreted in the urine.
