制备方法与用途

应用

4-溴-2-甲基苯酚主要用作有机合成与医药化学中间体。它可用于药物分子和消毒剂的合成以及实验室科学研究。

制备

将1 mmol邻甲基苯酚溶于3 mL乙醇中，然后向混合物中加入1.02 mmol重结晶提纯的N-溴代丁二酰亚胺。所得混合物在室温下搅拌1分钟，并用薄层色谱（TLC）监测反应进程，确保原料完全反应后，在减压下除去乙醇溶剂。

接着向反应体系中加入10 mL乙酸乙酯和10 mL蒸馏水，将混合物转移至分液漏斗中。分离有机相（乙酸乙酯），并用2 × 7 mL的乙酸乙酯萃取水层。合并所有乙酸乙酯提取物，并使用无水硫酸镁干燥。最后，通过旋干有机溶剂得到粗产物，再经柱层析分离纯化即可获得目标产物4-溴-2-甲基苯酚。

  多功能球蛋白脱卤过氧化物酶再次出现：EPA污染物氧化中同时的过氧化物酶和过氧化酶机制

  摘要：

  研究发现，来自三叶类多毛A蛇Amphitrite ornata的多功能催化血红蛋白脱卤过氧化物酶（DHP）可以催化H 2 O 2依赖性的EPA优先污染物（4- Me - o-甲酚，4-Cl- m-甲酚和五氯酚）的氧化。EPA有毒物质控制法案化合物（ø - ，米- ，p甲酚和4-氯离子ö甲酚）。生化分析（HPLC / LC-MS）表明形成了多种氧化产物，包括相应的邻苯二酚，2-甲基苯醌（2-MeBq）和氧化和/或脱卤程度不同的低聚物。使用4-BR- Ø-甲酚作为代表性底物，用18 O进行标记研究证实掺入邻苯二酚的O原子仅来自H 2 O 2，而掺入2-MeBq的O原子则来自H 2 O，与此一致单个底物分别被过氧合酶和过氧化物酶机制氧化。停止流动的紫外可见光谱研究强烈暗示了化合物I在导致儿茶酚形成的过氧化酶机制中的作用，以及化合物I和ES在产生2-MeBq产物的过氧化物酶机制中的作用。DHP与4-F-邻甲酚（1
