Soluble in hot ether, hot alcohol, slightly soluble in benzene, insoluble in petroleum ether, insoluble in water. Usage: used as pharmaceutical intermediates and flavor industry. 1, pharmaceutical: expectorant drugs can be used to prime the synthesis of the cuckoo. Coronary heart disease in the pharmaceutical industry for the production of intermediate treatment given Kexin, and local anesthetic used in the manufacture, fungicides, and hemostatic and so on; can inhibit the cervix The role of cancer; also be used to synthesize the anti-adrenergic drugs esmolol. 2, Agriculture: In the pesticide industry for the production of plant growth promoting agents, fungicides, and fresh fruits and vegetables long-term preservative. In addition, hydroxy acid can also be used to determine the uranium and hunger of the chemical reagents, for the production of photosensitive resin, the main raw material of ethylene plug oil hanging IV. 3, the chemical industry: 1) hydroxy acid is very important flavor and fragrance, allows the use of spices, primarily used to configure the spicy cherry, apricot, honey and other spices. Used in daily chemical industry in the preparation of soap and cosmetics fragrance. 2) hydroxycinnamic acid or a strong effect of the conductive material in the liquid crystal display industry, extensive research in recent years. Polyimide by hydroxy hydroxy acid and the grafting reaction of the hydroxy with photosensitive polyimide, and by IR, NMR to determine the photosensitivity of the hydroxyl polyimide structure. The synthetic hydroxy polyimide liquid crystal alignment layer as used in liquid crystal display, the demonstrated good thermal stability. 4, the cosmetics: hydroxy cinnamic acid on the tyrosinase enzyme and two single-phenol phenol activity was inhibited, resulting in a single phenol and two phenol enzyme activity decreased by 50%, used in cosmetics, which inhibit the formation of melanin. 5, the hydroxy acid new research direction: In recent years, many scientists at home and abroad will hydroxy acid is also committed to research and medical fields extended to the micro-organisms - cell differentiation and telomerase activity; cervical cancer inhibition. Hydroxy acid in the future will be more and more into our lives. The application of liquid crystal displays: Also has both a good orientation of liquid crystal in the liquid crystal phase transition temperature can have good thermal stability of the new materials. Orientation based technology for liquid crystal alignment layer have a variety of polymer materials, including polyimide (PI) is the most common and widespread use of the current liquid crystal alignment layer of a functional material. This is because the PI with a high temperature, corrosion resistance, high hardness, easy to film, good properties and low production costs, the industry can satisfy the requirements of alignment layer material properties. Because the display is high current, high power, high heat of a device, so the thermal stability of the device is essential, and this is precisely the weakness of PI. Professional production of hydroxy acid far the largest city of Science and Technology Corporation manufacturers of scientific research centers, well overcome this problem. The company R & D personnel by the hydroxyl is introduced into polyimide (PI) of the main chain or side chain, and then grafted with the reaction of hydroxy acid hydroxy polyimide, and by IR, NMR identified the hydroxyl polyimide structure. The synthetic hydroxy polyimide liquid crystal alignment layer used, not only proved to be very good thermal stability, but also greatly improve the orientation of liquid crystal substrate capacity, lack of technology to improve the parallel orientation. And its price is not higher than traditional materials. Purity: 99% min; Liquid Grade 99.9% Packing: 25kg net/bag. Brand: Nanjian
