L-5-Hydroxytryptophan Chemical Properties,Usage,Production

Chemical Properties

white to pale grey powder

Uses

A labelled metabolite of Tryptophan

Uses

5-Hydroxy-L-Tryptophan is a hydroxylated metabolite of L-Tryptophan

General Description

Colorless to pale pink crystals.

Air & Water Reactions

L-5-Hydroxytryptophan is sensitive to air. Slightly water soluble .

Reactivity Profile

L-5-Hydroxytryptophan reacts with bases. .

Fire Hazard

Flash point data for L-5-Hydroxytryptophan are not available, however, L-5-Hydroxytryptophan is probably combustible.

Purification Methods

Likely impurities are 5-hydroxy-D-tryptophan and 5-benzyloxytryptophan. Crystallise 5-hydroxy-L-tryptophan under nitrogen from water by adding EtOH. Store it under nitrogen. Also dissolve it in the minimum volume of hot H2O (~0.7g in 4mL) under nitrogen (charcoal) and allowed it to crystallise at 5o. The picrolonate crystallises from H2O with m 184-186o(dec).
