Dichlorodiphenyldichloroethylene (DDE) is a chemical compound formed by the loss of hydrogen chloride (dehydrohalogenation) from DDT, of which it is one of the more common breakdown products. [1] Due to DDT's massive prevalence in society and agriculture during the mid 20th century, DDT and DDE are still widely seen in animal tissue samples. [ 2 ]

The DE 4 is used to compute the amount of taxes to be withheld from your wages, by your employer, to accurately reflect your state tax withholding obligation.
