1.Discription:

D-Valine is white crystal or crystalline powder.Soluble in water, diluted acid and dilute base, insoluble in ethanol and ether.

Usage:It is an important organic chiral source mainly used in chiral medicine, chiral additive,and chiral auxiliary. It is used as chrial source of organic chiral synthesis in drugs manufacuture. As one optically active organic acid, it has the nonreplaceable function in certain chiral compound's asymmetric synthesis process. At present, it is mainly used as the methionine protecting agent in the new broad spectrum antibiotic, D- methane amino thiol and polypeptide synthetic process.

Storage: Store in a cool, dry place and keep away from direct strong light.
