L-phenylalanine is an essential amino acid, biologically active, human and animal itself can not be synthesized and must intake from outside, are 8 essential amino acids. It is an important biological nutrients which can be safely added to any food and beverage and aspartame as the main raw material of a variety of drugs and synthetic materials. The quality is stable, can be in the heat, air, light and long-term storage. L-phenylalanine is mainly used for: Synthetic aspartame (Aspartame) the main raw material, amino acids, pharmaceutical raw materials, manufacturing pharmaceutical intermediates, feed and food additives, synthetic vitamins and nutritional supplements, etc., in addition for synthesis of anticancer drugs, antiviral drugs, such as vitamin B6.

In recent years, L-phenylalanine in the pharmaceutical field of application has been growing attention from research discovery to clinical applications have a larger. Its main uses are: the production of hormone release promoting dipeptide heterocyclic drugs for the cure and prevention of osteoporosis; production endopeptidase inhibitors and thrombin inhibitors; production cardiovascular drugs, to treat diabetes, hypertension, , atherosclerosis, cardiovascular and other diseases; production of pharmaceutical intermediates tetrahydro-quinoline-3 - carboxylic acid; production of HIV (HTV-1) inhibitors; produce HIV protease (HIV) inhibitors (drugs Indinavir) key intermediate body (1S, 2R) -1 - amino-2 - indole and other products; production melphalan, etc., for the treatment of multiple myeloma, advanced ovarian cancer, some advanced breast cancer, polycythemia vera; ergotamine synthetic drugs, antibiotics and vitamins B6 important raw materials; L-phenylalanine can be used as the drug carrier of anti-cancer drugs directly into the tumor area molecule, the effect of other amino acids is 3 to 5 times. So that both can inhibit tumor growth, but also can reduce the side effects of drugs. Infusion of amino acids L-phenylalanine, composite amino acid preparation with L-phenylalanine. The future growth in the field of rapid development of market applications.
