L-tert-Leucine CAS 20859-02-3

L-tert-L-leucine (CAS 20859-02-3) is a non protein derived chiral amino acid, chemically named (S) -2-amino-3,3-dimethylbutyric acid. As an important chiral source, it is commonly used as a key precursor for chiral catalysts or ligands in asymmetric synthesis, for constructing chiral centers of complex molecules. In addition, it is also used as a nutritional enhancer in the fields of food and animal feed.
