代谢
氯硝苯被喂给了大鼠、奶牛和狗。在尿液中发现的代谢物是2,5-二氯-4-甲氧基酚,以自由和结合形式存在,可能是作为葡萄糖苷酸和硫酸盐。这在水解的粪便中没有检测到。在牛奶中没有发现代谢物。将氯硝苯与牛肝的10,000g超速离心上清液部分一起孵化后,观察到了相同的代谢物。在温室中种植的四季豆用(14)C-环标记的氯硝苯处理。对植物组织的分析表明存在2,5-二氯-4-甲氧基酚、2,5-二氯氢醌和2,5-二氯醌。
Chloroneb was fed to rats, cows and dogs. In urine, metabolite found was 2,5-dichloro-4-methoxyphenol in free and conjugated form probably as glucuronides and sulfates. This was not detected in hydrolyzed feces. No metabolites were found in milk. After incubation of chloroneb with 10,000g supernate fraction of beef liver, the same metabolite was observed. Snapbeans, grown in a greenhouse, were treated with (14)C-ring-labeled chloroneb. Analysis of plant tissues showed presence of 2,5-dichloro-4-methoxyphenol, 2,5-dichlorohydroquinone and 2,5-dichloroquinone.
