一般說明

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。

應用

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
