English description（英文原文，共 1162 字符）
Product Name:L-Aspartic Acid
English Name:L-Aspartic Acid
CAS No.:6899-03-2
Aliases:Aminosuccinic acid, 2-Aminobutanedioic acid, Asparaginic acid
Molecular Formula:C4H7NO4
Physical Properties:White crystalline powder, odorless, with a slight acidic taste. Slightly soluble in water, insoluble in ethanol and ether, soluble in dilute hydrochloric acid and sodium hydroxide solution. Melting point approximately 270-274°C (decomposition), relative density about 1.66.
Uses:Aspartic acid is one of the amino acids constituting proteins and participates in protein synthesis and glucose metabolism in living organisms. In pharmaceuticals, it is used in amino acid infusions, compound amino acid preparations, and auxiliary agents for liver function. In the food industry, it serves as a nutritional supplement and a synthetic raw material for sweeteners such as aspartame. It is also used to synthesize biodegradable materials such as polyaspartic acid.
Technical Specifications:
Content (on dry basis) ≥98.5%
Melting point 270-274°C (decomposition)
Specific rotation [α]D20 = +24.5° to +26.0° (c=5, 1M HCl)
Loss on drying ≤0.5%
Residue on ignition ≤0.1%
