L-ALANINE

L-ALANINE is a white crystalline powder or crystals with a slightly sweet taste. It is freely soluble in water and soluble in formic acid. L-ALANINE contains not less than 98.5 percent and not more than 101.0 percent of L-ALANINE (C3H7NO2). It is identified by comparing the infrared absorption spectrum of the sample with the standard. L-ALANINE meets stringent specifications for purity including limits for chloride, ammonium, sulfate, iron, heavy metals such as lead and arsenic. Related substance limits include maleic acid, malic acid and fumaric acid. L-ALANINE has low limits for loss on drying, residue on ignition and endotoxin. Assay tests confirm L-ALANINE content is between 98.5 to 101.0 percent. L-ALANINE is beneficial in the pharmaceutical industry as an intermediate for various drug formulations due to its high purity levels and specified limits on contaminants and related substances.
