English description（英文原文，共 1056 字符）
Product Name:L-Cysteine
English Name:L-Cysteine
CAS No.:52-90-4
Aliases:L-2-amino-3-mercaptopropionic acid, L-beta-mercaptoalanine, (R)-2-amino-3-mercaptopropanoic acid
Molecular Formula:C3H7NO2S
Physical Properties:White crystalline powder with a slight characteristic odor. Soluble in water, sparingly soluble in ethanol, insoluble in ether and other organic solvents. Melting point approximately 240°C (decomposes), monoclinic crystal system.
Uses:L-Cysteine is mainly used in the food industry as a nutritional supplement, antioxidant and stabilizer. It can be added to fermented flour products to improve dough texture and mouthfeel, and to natural fruit juices to prevent vitamin C oxidation and browning. In industry, it is used to produce amino acid derivatives, peptide compounds and other chemical products, and can serve as a catalyst or raw material in certain chemical reactions.
Technical Specifications:
Purity ≥99%
Melting point approximately 240°C (decomposes)
Loss on drying ≤0.5%
Residue on ignition ≤0.1%
Heavy metals ≤10ppm
