Aspartame CAS#22839-47-0

White crystalline powder, odorless, there is strong sweet, sweet and pure, sweetness of sucrose was 100-200 times. Melting point is 235℃ (decomposition). Amino acids is with the general nature. In dry conditions or pH value of 2 to 5 range, it is stability, strong acidic water solution can hydrolyzed to produce amino acid monomer, in neutral or alkaline conditions it can be cyclized to diketopiperazine. Solubility in water (25℃) is relevant to pH value, pH 7.0 was 10.2%, pH value 3.72 is 18.2%. At 25, isoelectric point is pH value of 5.2. Mice by oral LD50 > 10 g/kg Adl is 0~40mg/kg (FAO/who, 1994)

Product Application of Aspartame CAS#22839-47-0

The chemical name for aspartame is L-aspartyl-L-phenylalamine methyl ester.
It is a white crystalline powder and is about 200 times as sweet as sucrose. It is noted for a clean, sweet taste that is similar to that of sucrose.
Aspartame is the most widely used artificial sweetener in the world. It was approved by the FDA for use in the USA in 1981, and now is approved for use in several other countries of the world.
