Properties：D(-)-Asparagine monohydrate is white crystals or crystalline powder. Melting point: 275℃. Soluble in water (35g/L, 25℃).

Uses：D(-)-Asparagine monohydrate is a kind of pharmaceutical intermediate and can also be used in biochemical research and food additive. Its uses are as follows:

1. Nutritional supplements: It can be used as a cool-drink additive because when it is heated with sugar, an amino-carbonyl reaction occurs and it can form a special flavor substance.

2. Biochemical research: It can be used for the treatment of myocardial infarction, myocardial metabolic disorders, heart failure, heart block, fatigue and other diseases.

3. Others: Polypeptide synthesis, Substrate for aminotransferase measurement, Tuberculosis culture, Preparation of biological medium, Amino acid drugs, etc.

Storage：Stored in a well-closed and light-resistant container, and in a cool, dry and ventilated place

Packing：25kg fiber drum lined with plastic bag
