Applications / Functions of DL-Methionine powder
Suitable for the prevention and treatment of liver diseases and arsenic or benzene poisoning, DL-Methionine CAS 59-51-8 can also be used in the treatment of dysentery and chronic infectious diseases caused by protein deficiency and malnutrition.
- DL-Methionine powder is a feed nutrient fortifier.
- Nutritional supplements.
- DL-Methionine Raw Materials can be used as biochemical reagents, biochemical research; used in mixed isomer labelled mammalian and insect cell culture applications.
Physicochemical Property of DL-Methionine powder
DL-Methionine Raw Materials White flaky crystals or crystalline powder from alcohol, slightly sweet, with special smell. No optical rotation. Soluble in water, dilute acid and dilute alkali, slightly soluble in 95% alcohol, insoluble in ether.
Production methodprocess of DL-Methionine powder
In the presence of formic acid and copper acetate, propionaldehyde and methyl mercaptan condense to form 3-methylthiopropionaldehyde. Then mixed with sodium cyanide and ammonium bicarbonate solution.
Reacted at 90℃ to obtain methylthioethylglycolide. Without separation and purification, it can be heated to 180°C together with 28% sodium hydroxide solution and hydrolysed to produce sodium methionine. Neutralisation with hydrochloric acid gives DL-Methionine powder .
