Haimeng study Industrial Co., the manufacturer of high-quality, L- cysteine ??hydrochloride phone manufacturers, L- cysteine ??hydrochloride, CAS number, detailed description of L- cysteine ??hydrochloride, Shanghai L- cysteine ??hydrochloride latest offer price L- cysteine ??hydrochloride, the role of L- cysteine ??hydrochloride, L- cysteine ??hydrochloride factory distributor, L - cysteine ??hydrochloride manufacturers latest offer, the amount of L- cysteine ??hydrochloride, L- cysteine ??hydrochloride formula, L- cysteine ??hydrochloride molecular weight. English name: L-Cysteine ??monohydrochloride. Formula: C3H7NO2S HCl H2O??. Molecular Weight: 175.64. CAS: 52-89-1. Properties: colorless to white crystal or crystalline powder, with slight odor of sour, melting point 175 ℃ (decomposition) hair. Dissolved in water, acidic aqueous solution, 1% pH of the solution is about 1.7,0.1% solution pH of about 2.4. Also soluble in alcohol, ammonia and acetic acid, insoluble in ether, acetone, benzene. With the reduction, it has antioxidant and prevent non-enzymatic browning. Sources and methods: The hair was hydrolyzed with hydrochloric acid, vacuum distillation, after hydrochloric acid distillate by bleaching, filtration, the filtrate add ammonia to obtain crude L- cystine crystals dissolve in ammonia and then, after recrystallization, with hydrochloric acid and then dissolving the electrolytic reduction, concentrated, cooling and crystallization, drying. The main purpose 1, cysteine ??hydrochloride can be dissolved in water to form injection or tablets can be quickly absorbed by the body. It is the main raw material carboxymethyl cysteine ??and acetyl cysteine ??production. [1] 2, in the clinical to treat leukopenia, and due to the administration of anti-cancer drugs and radiopharmaceuticals caused leukopenia, and heavy metal poisoning antidote. In addition, for the treatment of toxic hepatitis, thrombocytopenia, skin ulcers, and can prevent liver necrosis, bronchitis and phlegm therapeutic effect on propylene Qinghe aromatic poisoning detoxification, the prevention of radiation injury in 3 bread improvers: to promote fermentation, to prevent oxidation of. In terms of food as bread crash accelerator, can change the flavor of bread and food. 4, can be used in cosmetics cosmetics perm fine, sunscreen, hair growth and hair conditioners perfume and the like. 5, nutritional supplements, antioxidants, color fixative: for natural fruit juice, vitamin C to prevent oxidation and discoloration. Use and precautions: flour treatment agent, nutritional supplements. As a nutritional supplement, added in an amount not to exceed 2.3% of the total protein content (including L- cystine). China's "food additives health standards" (GB2760-1996) provides that: for fermented flour products, 0.06g / kg. Dosage: specific use may be added to the flour mix, or added in the dough. Typically, the dosage for bread 0.02 ~ 0.045g / kg; for natural fruit juice, vitamin C prevents oxidation and browning, the amount of 0.2 ~ 0.8g / kg.
