【Function】 D-Valine is one important organic chiral source and is mainly applied in chiral medicine, chiral additive, helping the medicinal preparation and so on. It uses as chrial source of chiral synthesis in drugs manufacuture. As a organic acid with optics activeness, it can not be substated in asymmetrical synthesis of some chircal compound. Now it mainly uses as valine protecting agent that applies in processing new broad spectrum antibiotic, D-valinol and multi-peptides.
