Function
D-alanine is one important organic chiral source, it is used in chiral medicine, chiral additives, and it is chiral source of chiral
synthesis in pharmaceutical and food industry. As one organic acid with optical activity, D-alanine has irreplaceable function in
some chiral chemical compound `s asymmetrical combined sequence. And now, D-alanine is used to manufacture new kind of
broad-spectrum antibiotic, D-alaninol and compound new sweetness-Alitame.
Application
Animal Pharmaceuticals, Medical Raw Material & Food Additive
