Main functions and applications: D-methionine is an important organic chiral source containing sulfur, which is mainly used in chiral drugs, chiral additives, chiral auxiliaries and other fields. As an optically active organic acid, it plays an irreplaceable role in the asymmetric synthesis of some chiral compounds. At present, it is mainly used to produce new broad-spectrum antibiotics, D-methylthionine, and methionine protectant in the peptide synthesis process.
