Overview | 4-fluorocinnamic acid (4-FCA), commonly used in pharmaceutical intermediates The synthesis of compounds such as fluorocinnamic acid, malonic acid and pyridine. Because of its best application limit is low, low molecular viscosity, good permeability, high resistivity, extremely high voltage retention rate, high stability, high melting point, it can meet a wide working temperature range, high photosensitivity, and photolysis speed, etc. It is widely used in the electronic liquid crystal industry. |
features | p-fluorocinnamic acid has low molecular viscosity, good permeability, high resistivity, high stability, meeting the requirements of working at most temperatures, high photosensitivity, and response The short time makes the brightness, luminosity and color saturation of the liquid crystal display better than the traditional material fluorocinnamic acid because of its low molecular viscosity. |
Application | p-fluorocinnamic acid (commonly used in the synthesis of pharmaceutical intermediates such as fluorocinnamic acid, malonic acid and pyridine. Mainly used in the synthesis of industrial fragrances, the synthesis of pharmaceutical intermediates, such as the synthesis of malonic acid, fluorocinnamaldehyde and pyridine, and also used in the electronic information industry as a photosensitive agent. In the liquid crystal display industry abroad has gradually used p-fluorocarbonic acid to replace the traditional polymer material, the use of p-fluorocarbonic acid as liquid crystal material can make the response time of the display increased to less than 16ms, and in the temperature range of -20 ℃ to 50 ℃ can be used normally. In addition to the excellent performance of the product, the material is easy to store, produce, and transport, and the price is low, so it is considered to be the most outstanding, most advanced and most popular liquid crystal material. |
