white powder | [Uses]
N-Acetyl-DL-tryptophan is produced via chemical synthesis using the standard amino acid, tryptophan. It can be used in downstream applications of biopharmaceutical production as a transfer agent or stabilizer. | [Definition]
ChEBI: An N-acetylamino acid that is the N-acetyl derivative of tryptophan. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
A likely impurity is tryptophan. Crystallise it from EtOH by adding water. [Cowgill Biochim Biophys Acta 200 18 1970, DL: Berg J Biol Chem 100 79 1933, Beilstein 22/14 V 40-50.] |
