D- valine is an important organic chiral source, which is mainly used in the fields of chiral intermediates, chiral additives and chiral auxiliaries, and is used as chiral source for chiral synthesis in pharmaceuticals. As an optical active organic acid, it has an irreplaceable role in the asymmetric synthesis of some chiral compounds, and is currently used to produce valine protectants in the synthesis of new broad-spectrum antibiotics, D- valerine and polypeptide. It is also used for the synthesis of sweetener Allan.
