MeltingPt = 200 °C (decomposes)Endrin is a cyclodiene
insecticide used oncotton ,maize , andrice . It also acts as anavicide . As arodenticide , it is used to control mice andvole s. It is a solid, cream to light tan to white, almost odorless substance. It melts and decomposes at 200 °C. It is moderately soluble inbenzene andacetone , slightly soluble inalcohol s,alkane s, andxylene , and almost insoluble in water. It is also known as Mendrin, and Compound 269.The use of endrin is now banned in many countries.
The majority of use (about 80%) was as a spray to control insect pests of cotton. It was also used on rice, to some extent on
sugar cane , in a limited way ongrain crops andsugar beet s, and in Australia ontobacco andcole crops . It was occasionally used inorchard s as a control ofrodent s, where it is sprayed on the ground under the trees in autumn or spring, often as a solution in mineral oil. As a seed treatment, it was used for cotton seed in the United States, and for beans seeds in Australia.Endrin is a
stereoisomer ofdieldrin and is structurally similar toaldrin , andheptachlor epoxide .It is likely to adsorb onto the sediments in surface water. It can
bioaccumulate in tissues, particularly fatty tissues, of organisms living in water. Some estimates indicate itshalf-life insoil for over 10 years. It is very toxic to aquatic organisms, namelyfish , aquaticinvertebrate s, andphytoplankton . [ [http://pops.gpa.unep.org/12endr.htm] ]Acute endrin poisoning in humans affects primarily the
nerve system . Food contaminated with endrin caused several clusters of poisonings worldwide, especially affecting children. [ [http://www.prn2.usm.my/mainsite/bulletin/nst/1998/nst4.html] ]In comparison with dieldrin, the degree of persistence of endrin in organisms is lower, likely due to its rapid excretion in
bile . It is eliminated mostly infeces . [ [http://www.inchem.org/documents/jmpr/jmpmono/v070pr13.htm 1970 Evaluations of some pesticide residues in food] ]ee also
