English description（英文原文，共 1106 字符）
Product Name:L-Asparagine
English Name:L-Asparagine
CAS No.:70-47-3
Aliases:2-Amino-3-carbamoylpropanoic acid
Molecular Formula:C4H8N2O3
Physical Properties:White orthorhombic crystals or crystalline powder with a slight sweet taste. Melting point approximately 234°C. Soluble in water (3 g/100 mL at 25°C), almost insoluble in ethanol and ether; the aqueous solution is acidic. Hydrolyzes to aspartic acid upon treatment with alkali, and its aqueous solution also decomposes when heated. Molecular weight: 132.12.
Uses:Used as a nutritional supplement and as an amino acid-based pharmaceutical. It is widely applied in the preparation of biological culture media, peptide synthesis, transaminase substrate assays, and tuberculosis culture. It can also be used for treating acrylonitrile wastewater and as an organic synthetic raw material or pharmaceutical intermediate.
Technical Specifications:
Purity ≥99%
