Application of D-Valine CAS 640-68-6
D - Valine is an important source of a machinist sex, mainly used in chiral intermediates, chiral additive, chiral auxiliaries and other fields, in the pharmaceutical as chiral synthesis of chiral source. As a kind of optical activity of organic acids, in some of the asymmetric synthesis of chiral compounds has an irreplaceable role in the process, at present mainly for the production of new broad spectrum antibiotics, D - valerian ammonia alcohol, peptide synthesis process of Valine protective agent. Also used for synthetic sweeteners revised.
