Usage:

1. Medicine

It can be used in the synthesis of rhododendrine, an expectorant new drug.It has the function of inhibiting cervical cancer.It can also be used to synthesize the adrenergic drug ethylol.

2. Agriculture

It is used in the pesticide industry to produce plant growth promoters, long-term fungicides and fresh-keeping preservatives of fruits and vegetables.In addition, p-hydroxycinnamic acid can also be used as a chemical reagent for the determination of uranium and hunger.

3. Cosmetics

Hydroxycinnamic acid can inhibit the activity of tyrosinase monophenolase and diphenylase, resulting in a 50% reduction in the activity of monophenylase and diphenylase, and inhibiting the production of melanin in cosmetics.

4. Chemical industry

1) it is a very important flavor for hydroxyl cinnamic acid. The permitted use of spices is mainly used to prepare spices such as fragrant cherries, apricots and honey.In the daily chemical industry used to prepare soap and cosmetics fragrance.

2) p-hydroxycinnamic acid is also a strong conductive material, which has been widely studied in the LCD industry in recent years.The photosensitive p-hydroxypolyimide was synthesized by the graft reaction of hydroxypolyimide and p-hydroxycinnamic acid.The synthesis of p-hydroxypolyimide as liquid-crystal oriented layer is used in the liquid crystal display device, which proves that it has good thermal stability.
