Endosulfan is an organochlorine acaricide and insecticide that is currently being phased out of use worldwide. Since it is off-patent, it is very cheap. This compound has two isomers, exo and endo known as II and I respectively. Endosulfan sulfate is produced by oxidation having an extra O atom attached to the S atom. Because of its severe toxicity, potential for bioaccumulation and part as a disrupter of endocrine, it has become greatly controversial. Endosulfan poses serious threats to the environment and human health and because of this, a global ban on the use and production of this insecticide is being considered under the Stockholm Convention of April 2011.
