L-tert-Leucine Chemical Properties,Usage,Production

Description

L-tert-Leucine is an essential amino acid making up one third of our muscle protein. L-tert-leucine is important in developing chiral pharmaceutically active chemicals. It can be used as a food additive. It is used in the formation of sterols. It can also be used as the catalyst in the production of cobalt oxazoline palladacycles complex. It can also be used for the production of Chiral tridentate Schiff base ligands.
