N- octyl-bicyclohepten-dicarboximid or MGK 264 is a chemical compound that belongs to the group of dicarboximides and acts both as a repellent and as a synergist against insects. MGK-264 was developed by McLaughlin Gormley King as a cheap alternative to piperonyl butoxide and was first approved in the USA in the late 1940s.
Extraction and presentation
The compound can be obtained from 2-ethylhexylamine and 5-norbornene-2,3-dicarboxylic acid anhydride.
Admission
N- octyl-bicyclohepten-dicarboximid is not considered a plant protection product within the meaning of Directive 91/414 / EEC or Regulation (EC) No. 1107/2009 (Plant Protection Product Regulation) . In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
