Main Functions and Use ：
D-Threonine is one kind of important organic chiral source, mainly applies in the chiral medicine, chiral chemical additive, chiral auxiliary and so on domains; In the pharmacy, it is used as the chiral source for the chiral synthesis. As one optically active organic acid, it has the nonreplaceable function in certain chiral compound's asymmetric synthesis process. At present, it is mainly used as the threonine protecting agent in the new broad spectrum antibiotic, D- propyl amine alcohol and polypeptide synthetic process. |
