2. The application of Pharmaceutical Intermediates, Expectorants Farrerol Intermediates. 

In the pharmaceutical industry for the production of coronary heart disease treatment Kexin set intermediate, as well as for the manufacture of local anesthetic agents, fungicides, and hemostatic and so on. 

3. For Hydroxy Acid Applications in Agriculture
In the pesticide industry for the production of plant growth-promoting agent, long-lasting anti-fungicides and fresh fruits and vegetables with the agent. In addition, the cinnamic acid is also used for determination of uranium and hunger of chemical reagents for the production of photosensitive resin, the main raw materials of ethylene Cypriot oil hanging 4. Cinnamic acid is not only a few acids spices. 


4. 
4-Hydroxycinnamic Acid in the Chemical Industry the Application of
4.1. 
4-Hydroxycinnamic Acid is very important to flavors and fragrances, allowing the use of edible spices, mainly used for the preparation of spicy cherry, apricot, honey and spices to wait. In daily chemical industry, for the preparation of soap and cosmetics flavor.
4.2 Through the hydroxyl polyimide with the graft-hydroxy cinnamic acid synthesized by the reaction of the hydroxy with a photosensitive polyimide, and by infrared, nuclear magnetic resonance to determine the photosensitivity of the hydroxyl polyimide structure. The synthetic-hydroxy polyimide liquid crystal alignment layer, as used in the liquid crystal display devices, it is proved that they have good thermal stability. 


5. 
4-Hydroxycinnamic Acid New Research Directions
In recent years, many scientists at home and abroad are also committed to extending research  to hydroxy acid micro-organisms and medical fields - cell differentiation and telomerase activity; cervical cancer in vivo. Hydroxy cinnamic acid in the future will be more and more into our lives.
