WGK Germany 3 RTECS YV9360000 TSCA Yes HS Code 2922491990D-Valine (H-D-Val-OH) (CAS: 640-68-6) is the D-form of valine, being the non-proteinogenic isomer of valine. D-Valine is an important organic chiral source, mainly used in chiral drugs, chiral additives, chiral additives and other fields. As an optically active organic acid, D-Valine plays an irreplaceable role in the asymmetric synthesis of some chiral compounds, at present mainly for the production of new broad spectrum antibiotics, D-Valerian ammonia alcohol, peptide synthesis process of Valine protective agent. Used as pharmaceutical raw materials and pharmaceutical intermediates, and also used in the synthesis of sweetener Alatan. Used as a selective inhibitor of cell proliferation in cell culture to inhibit cells lacking dextrorotatory amino acid oxidase. D-Valine can also be used for biochemical research. D-Valine is the intermediates for fluvalinate. D-Valine are also important raw materials as chiral drugs for example it may be used for the synthesis of antineoplastic drugs, anti-diabetes and its complications drugs. With the expansion of the applications fields as well as market demanding of D-Valine, the preparation of D-Valine will become a hot research field on amino acid.
