多氯雙苯駢對戴奧辛

多氯代雙苯駢對戴奧辛（polychlorinated dibenzo-p-dioxins）是對戴奧辛（對二㗁己熳）衍生物中最重要、危害最大的一類，是二苯駢對戴奧辛的氯代物，一般提到「戴奧辛」時指的均是對戴奧辛衍生物中的此一子類，包含臭名昭著的橙劑雜質2,3,7,8-四氯雙苯環戴奧辛（2,3,7,8-TCDD）。

化合物列表

二苯駢對戴奧辛的取代位編號示意圖，由於5位和10位被氧給雜了，至多可以有八個氫被代。在2,3,7,8上用四個氯取代即是著名的2,3,7,8-四氯雙苯環戴奧辛。

二苯駢對戴奧辛含有兩個苯環和兩個氧橋，形成芳香二醚。命名中的「二㗁」指

由於二苯駢對戴奧辛的5位和10位被氧給雜了，至多可以有八個氫被代。存有凡75種多氯雙苯駢對戴奧辛的（不同分）異構物。^[1]
