L-Cysteine hydrochloride monohydrate USP is used as a precursor in food, and personal care products. It is actively involved in the production of flavors such as meat flavor obtained by reacting with sugars. It plays an important role as a key raw material for the manufacture of N-acetyl-L-cysteine, S-carboxymethyl-L-cysteine and L-cysteine base. It is involved in the treatment of liver disease as an antioxidant and antidote. Being an essential amino acid, it used as animal feed especially for sheep, which is responsible the growth of wool. U.S.P. A chemical grade of sufficient purity to meet or exceed requirements of the U.S. Pharmacopeia (USP); acceptable for food, drug, or medicinal use; may be used for most laboratory purposes.

DL-Methionine CAS No: 59-51-8 Molecular formula: C5H11NO2S Molecular weight: 149.21 Product standard: AJI-92/97 Version, EP-4 Version, USP-24/26 Version, FCC-4 Version Properties: White flaky crystal or crystalline powder. Has special smell. Slight sweet taste. Melting point: 281 degree C(decompound). 10% aqueous solution's pH value is 5.6-6.1. No optical rotation, stable to heat and air. Unstable to strong acid, can cause the demethylation. Soluble in water(3.3G/100ml, 25degree C), diluted acid and diluted alkali solution. Very hard to dissolve in ethanol, almost does not dissolve in ether. Use: DL-Methionine is one of the basic units for composing the protein, is the only sulfur bearing amino acid among the essential amino acids, it participated in the transmethylation interior the animal body, the phosphorus metabolism and the adrenalin, choline and creatine synthesis, it also is the raw material of the protein and cystine synthesis. Methionine is unable to synthesize in the animal body, must take in from food. Adds it in the feed, can promote the poultry to grow, increase lean meat quantity and reduce the feeding cycle.
