WGK Germany 1 RTECS YN6129200 FLUKA BRAND F CODES 8 TSCA Yes HS Code 2922491990DL-Tryptophan (H-DL-Trp-OH) (CAS: 54-12-6), amino acids derivatives, used in peptide synthesis, organic synthesis intermediates, pharmaceutical intermediates, biochemical reagents, chemical reagents. DL-Tryptophan, sensitive to light. It is stable in lye and decomposes in strong acid. Soluble in alkaline hydroxide solution, soluble in hot ethanol, insoluble in chloroform, soluble in dilute hydrochloric acid. DL-Tryptophan is an amino acid precursor of serotonin and melatonin. It is a dietary supplement for use as an antidepressant, anxiolytic, and sleep aid. DL-Tryptophan also can be used as feed nutrition enhancer, antioxidants. DL-Tryptophan is a feed nutrition fortifier, which can significantly increase the internal antibody of animal fetus and promote the lactation of dairy cows and sows during lactation. When animals lack tryptophan, growth arrest, weight loss, and fat accumulation are reduced. Mainly used in artificial milk of piglets, a small amount of sows and laying hens, the general dosage is 0.02%-0.05%. Nutritional supplement. Antioxidants can be added to foods with low tryptophan content such as gelatin and corn.Flow Chart of the DL-Tryptophan:
