Uses:Pharmaceutical intermediates, pigment intermediates cuckoo expectorants
1, medicine: expectorant drugs can be used to prime the synthesis of the cuckoo, the production set satisfying coronary heart disease drugs intermediates, and the manufacture of local anesthetics, such as fungicides and hemostatic; inhibit the role of cervical cancer; also be used to synthesize anti-adrenergic drugs esmolol.
2, agricultural: for the production of plant growth-promoting agents, long-lasting fresh fruits and vegetables fungicides and preservatives. There is also the hunger for the determination of uranium and the chemical reagents used in the production of the main raw material ethylene photosensitive resin oil plug hanging four.
3, the chemical aspects: (1) is mainly used for configuration spicy cherry, apricot, honey and other spices. In the Japanese chemical industry for the preparation of soap and cosmetics fragrance. (2) hydroxyl polyimide with hydroxy cinnamic acid was synthesized by grafting reaction of hydroxyl with photosensitive polyimide, and by IR, NMR to determine the photosensitivity of the hydroxyl polyimide structure. The synthesis of 3 - hydroxy polyimide liquid crystal alignment layer as used in liquid crystal display devices, the demonstrated good thermal stability.
4, cosmetics: the enzyme tyrosinase, one phenol and two phenol inhibit enzyme activity, resulting in a single phenol and two phenol enzyme activity enzyme activity decreased by 50%, used in cosmetics which inhibit melanin production.
5, will be extended to micro-organisms and medical research fields - cell differentiation and telomerase activity.
