Hazard Note Irritant
D-Proline (H-D-Pro-OH) (CAS: 344-25-2) is the D-enantiomer of proline. Amino acids and derivatives, used in peptide synthesis, used as an organic synthesis intermediate, pharmaceutical intermediate, can be used as a chiral intermediate, biochemical reagent or chemical reagent. Used in the synthesis of drugs and food and feed additives. D-Proline is an endogenous metabolite.
D-amino acid is an important class of chiral reagents and chiral intermediates. At present, most of the production of D-amino acids is to prepare racemates by synthetic methods, and then split to obtain optical isomers.
