5-METHYL-DL-TRYPTOPHAN Usage And Synthesis
Chemical Propertiesoff-white powder
DefinitionChEBI: 5-methyltryptophan is a tryptophan derivative that is tryptophan substituted by a methyl group at position 5 of the indole ring. It is a non-proteinogenic alpha-amino acid and a tryptophan derivative.
Purification MethodsCrystallise dl-5-methyltryptophan from aqueous EtOH after dissolving it in aqueous NaOH, precipitating with AcOH, filtering the solid off and drying for 24hours at 50o. [Jackman & Archer J Am Chem Soc 68 2105 1946, Beilstein 22 IV 6815.] The picrate crystallises from MeOH with m 202o(dec). The N-phenylcarbamoyl derivative crystallises from aqueous MeOH with m 202o. [Gordon & Jackson J Biol Chem 110 151, 154 1935.]
