It is usually used as a raw material for fragrant, which can make the aroma of the main spice more volatile. Second, the pharmaceutical industry In the pharmaceutical industry, the important drugs used in the treatment of coronary heart disease are lactamidine and Xintongping, and chloramphenicol and cinnamophenazine, which are used to make "Xinan'an", a local anesthetic, bactericide, hemostatic Medicine, etc. It can also synthesize chloramphenicol and cinnamophenazine, used as spinal cone relaxant and antispasmodic. Mainly used for cerebral thrombosis, cerebral arteriosclerosis, coronary arteriosclerosis and other diseases. Can significantly inhibit the proliferation of lung adenocarcinoma cells. 3. Organic Synthesis In organic chemical synthesis, cinnamic acid can be used as a slow-release agent for galvanized sheet, a heat stabilizer for polyvinyl chloride, a crosslinking agent for polyurethane, a flame retardant for hydantoin and polycaprolactam, and a chemical analysis reagent. It is also a reagent for the determination of uranium and vanadium separation; it is also the main synthetic raw material of negative-type photosensitive resin. It mainly synthesizes laurate, polyvinyl alcohol cinnamate, polyvinyloxycinnamate and epoxy resin with pendant cinnamate. Used in plastics, it can be used as heat stabilizer for PVC, bactericidal, mildew and deodorant. It can also be added to rubber and foam plastic to make deodorant shoes and insoles. It can also be used for cotton and various synthetic fibers, leather, paint , Shoe polish, straw mat and other products to prevent mildew.
