Agent Orange: mixture of herbicides used [as a defoliant during the Vietnam War] ... consisted of approximately equal amounts of the unpurified butyl esters of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). Agent Orange also contained small, variable proportions of 2,4,7,8-tetrachlorodibenzo-p-dioxin (commonly called "dioxin"), which is a by-product of the manufacture of 2,4,5-T.
