Chemical name: D-hydroxybutyric acid
Molecular formula: C4H9NO3
Molecular weight: 119.12
Properties: white crystal or crystalline powder; Easily soluble in water, insoluble in ethanol, ether, chloroform; It tastes sweet.
Application: D-threonine is an important organic chiral source, 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-threonine, and threonine protectors in the peptide synthesis process.
