L-5-Hydroxytryptophan Chemical Properties,Uses,Production
Chemical Properties
white to pale grey powder
Uses
A labelled metabolite of 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.
Trade name
Levothym (Promonta Lundbeck, Germany), Lévotonine (Panpharma, France), Oxyfan (Coli, Italy), Tript-OH (Sigma- Tai, Italy).
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).
