چکیده
The title compound, C(20)H(18)Cl(2)F(2)N(2)O(5), is considered to belong to the fourth generation of insecticides with properties such as high selectivity, low acute toxicity for mammals and high biological activity. An intramolecular N-H⋯O hydrogen bond results in the formation of a six-membered ring. In the crystal structure, intermolecular N-H⋯O and C-H⋯F hydrogen bonds link the molecules.

1. A single oral dose of either [(14)C]Prefix or 2,6-dichlorobenzo[(14)C]nitrile to rats is almost entirely eliminated in 4 days: 84.8-100.5% of (14)C from [(14)C]Prefix is excreted, 67.3-79.7% in the urine, and 85.8-97.2% of (14)C from 2,6-dichlorobenzo-[(14)C]nitrile is excreted, 72.3-80.7% in the urine. Only 0.37+/-0.03% of the dose of [(14)C]Prefix and 0.25+/-0.03% of the dose of 2,6-dichlo...
