L-Tryptophan Chemical Properties,Usage,Production

Chemical Properties
White to off-white crystalline powder

General Description
White powder with a flat taste. An essential amino acid; occurs in isomeric forms.

Air & Water Reactions
Slightly soluble in water.

Reactivity Profile
Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition L-Tryptophan emits toxic fumes.

Fire Hazard
Flash point data for L-Tryptophan are not available. L-Tryptophan is probably combustible.
