DESCRIPTION
L-Phenylalanine occurs as colorless or white, platelike crystals or as a white crystalline powder. One gram is soluble in about 35 mL of water. It is slightly soluble in alcohol, in dilute mineral acids, and in alkali hydroxide solutions. It melts with decomposition at about 283°. The pH of a 1:100 aqueous solution is between 5.4 and 6.0.
Function: Nutrient.
REQUIREMENTS
Identification: The infrared absorption spectrum of the sample exhibits relative maxima at the same wavelengths as those of a typical spectrum as shown in the section on Infrared Spectra, using the same test conditions as specified therein.
Assay: Not less than 98.5% and not more than 101.5% of C9H11NO2, calculated on the dried basis.
Lead: Not more than 5 mg/kg.
Loss on Drying: Not more than 0.2%.
