一般描述
2,6-二氯-1,4-苯醌（DCBQ，2,6-DCBQ）是一种卤代苯醌。卤代苯醌是在饮用水中发现的一类消毒副产物（DBP）。它们能够产生活性氧，并对T24人膀胱癌细胞中的蛋白和DNA造成氧化损伤。紫外线所引起的饮用水中DCBQ的转化已被报道。已报道可通过液相色谱-ESI串联质谱法检测饮用水中的DCBQ。
应用
2,6-二氯-1,4-苯醌可作为一种适用的试剂，用于通过单电位步进计时电流法对乙腈中的醌、硝基芳族化合物、二茂铁和芳烃化合物家族扩散系数（D）进行研究。它可用于制备：
- 2,3,5-三氯-1,4-二氢醌
- 2,3,5-三氯-1,4-苯醌
- 2,6-二氯-1,4-二氢醌

Halobenzoquinones (HBQs) are a group of emerging disinfection byproducts (DBPs) found in treated drinking water. Because the use of UV treatment for disinfection is becoming more widespread, it is important to understand how the HBQs may be removed or changed

The metal-independent decomposition of organic hydroperoxides and the formation of organic alkoxyl radicals in the absence or presence of halogenated quinones were studied with electron spin resonance (ESR) and the spin-trapping agent 5,5-dimethyl-1-pyrroline N-oxide (DMPO). We found that 2,5-dichloro-1,4-benzoquinone (DCBQ)
