Production method
1. Indole was condensed to form 3-dimethylaminomethyl indole, and then condensed to form ethyl α – carboxylate – β (3-indole) – N-acetyl – α – alanine ethyl ester, which was hydrolyzed, decarboxylated and then hydrolyzed to form DL tryptophan.
2. Tryptophan was synthesized from indole in high concentration of pyruvic acid and ammonia under the catalysis of enzyme. Or it is prepared from indole and acetylamino malonate.We believe that long term partnership is a result of high quality, value added service, rich experience and personal contact for China Cheap price China 99% 4, 6-Diaminoresorcinol Dihydrochloride CAS 16523-31-2 Industry Grade, In case you have the requirement for almost any of our items, make sure you call us now.
