在常温常压下保持稳定,应避免与氧化物接触。
2,3,5,6-四氟苯酚是一种重要的有机二元醇,作为广泛应用的有机原料,在有机合成工业中是基础原料;此外,它还可用于生产润滑剂、增塑剂;在医药及有机中间体合成等方面也有应用;同时,也可用于液晶材料、可降解功能高分子材料、香料、润滑油、油墨、涂料、化妆品、增塑剂以及各种添加剂的制造。
合成方法向1升玻璃反应釜中加入404克N,N-二甲基甲酰胺(DMF)和202.3克乙酸钠,将温度控制在50-55°C。然后缓慢加入106.0克五氟苯甲酸并升温回流反应6小时。使用HPLC检测反应液中原料含量低于1.0%,降温至80°C以下后,在反应釜中加入350.0克30%浓盐酸,调节pH值小于1。继续回流反应5小时。完成后进行水蒸气蒸馏,分离出下层有机物。经精馏得到74.0克2,3,5,6-四氟苯酚,降温后变为白色结晶,收率为89%,HPLC纯度为99.9%。
储存2,3,5,6-四氟苯酚必须密封避光保存,避免与空气接触。应储存在阴凉、通风的库房中,并远离火源和热源以及强碱性试剂。仓库温度不宜过高,一般不超过26℃。此外,还需与其他化学品分开存放,禁止混存,不宜大量储存或久存。

When innate immune cells such as macrophages are challenged with environmental stresses or infection by pathogens, they trigger the rapid assembly of multi-protein complexes called inflammasomes that are responsible for initiating pro-inflammatory responses and a form of cell death termed pyroptosis. We describe here the identification of an intracellular trigger of NLRP3-mediated inflammatory signaling, IL-1β production and pyroptosis in primed murine bone marrow-derived macrophages that is mediated by the disruption of glycolytic flux. This signal results from a drop of NADH levels and induction of mitochondrial ROS production and can be rescued by addition of products that restore NADH production. This signal is also important for host-cell response to the intracellular pathogen Salmonella typhimurium, which can disrupt metabolism by uptake of host-cell glucose. These results reveal an important inflammatory signaling network used by immune cells to sense metabolic dysfunction or infection by intracellular pathogens.
