English description（英文原文，共 945 字符）
Product Name:L-Alanine
English Name:L-Alanine
CAS No.:56-41-7
Aliases:L-2-Aminopropionic acid, L-α-Alanine, (S)-2-Aminopropanoic acid
Molecular Formula:C3H7NO2
Physical Properties:Colorless to white needle-like crystals or crystalline powder with a sweet taste; freely soluble in water (16.72 g/100 mL at 25°C), slightly soluble in ethanol; pH of 5% aqueous solution 5.5–7.0; chemically stable, melts and decomposes at about 295–300°C.
