Dechloranes are a class of highly chlorinated norbornene compounds, synthesized by the Diels-Alder reaction of hexachlorocyclopentadiene with various substrates. Dechlorane is actually a trade name for Mirex, indicating its use as a flame retardant compound as opposed to its more commonly known use as an insecticide. Dechlorane was used as a flame retardant until the late 1970s when Mirex was banned. As an alternative industry turned to other related compounds such as Dechlorane Plus (DP), Dechlorane-602 (Dec-602), Dechlorane-603 (Dec-603), and Dechlorane-604 (Dec-604) to meet the needs of the growing flame retardant application.
