Main Functions and Uses:

D-Methionine is an important sulfur-containing organic chiral source, mainly used in the fields of chiral drugs, chiral additives, and chiral auxiliaries. As an optically active organic acid, it plays an irreplaceable role in the asymmetric synthesis of certain chiral compounds. It is currently primarily used in the production of new broad-spectrum antibiotics, D-methioninol, and as a methionine protecting agent in peptide synthesis processes.
