多氯双苯并对二𫫇英

多氯代双苯并对二𫫇英（polychlorinated dibenzo-p-dioxins）是对二𫫇英（对二𫫇己熳）衍生物中最重要、危害最大的一类，是二苯并对二𫫇英的氯代物，一般提到“二𫫇英”时指的均是对二𫫇英衍生物中的此一子类，包含臭名昭著的橙剂杂质2,3,7,8-四氯雙苯環二噁英（2,3,7,8-TCDD）。

化合物列表

二苯并对二𫫇英含有两个苯环和两个氧桥，形成芳香二醚。命名中的“二𫫇”指两个氧杂。

由于二苯并对二𫫇英的5位和10位碳原子被氧原子置换，至多可以有八个氢被取代。存有凡75种多氯双苯并对二𫫇英的（不同分）异构体。Nomenclature and physico-chemical properties of PCDDs and PCDFs. In: Dioxins in the Environment: What are the health risks? INSERM Collective Expert Evaluation Reports (2000) . Ncbi.nlm.nih.gov (2011-03-18). Retrieved on 2011-06-09.
