N-Acetyl-DL-tryptophan Chemical Properties,Uses,Production

Chemical Properties

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.

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.]
