Mirex is a fully chlorinated organic compound, based on two linked five member carbon rings. It is highly stable, doesn't burn easily or react readily with acids, bases, chlorine or ozone. It was first synthesized in 1946 by Prins but was not used in pesticide formulation until 1955. Mirex is manufactured by the dimerization of hexachlorocyclopentadiene in the presence of aluminium chloride. Because of its high melting point, mirex was used as a fire retardant in plastic, rubber, paint, paper and electronics. It is also used as a stomach insecticide. It has also been used to combat leaf cutters in South America, harvester termites in South Africa, mealy bug of pineapple in Hawaii.
