D-Threonine Use and Manufacturing
A steroisomer of the proteinogenic amino acid L-threonine.D-threonine is an important organic chiral source, mainly used in the fields of chiral drugs, chiral additives, chiral auxiliaries, etc., as a chiral source for chiral synthesis in the pharmaceutical industry. As an optically active organic acid, it has an irreplaceable role in the asymmetric synthesis of certain chiral compounds. It is mainly used to produce new broad-spectrum antibiotics, D-threonine, and threonine protection in peptide synthesis. Agent.
