white fine crystalline powder
A useful chiral building block for peptide synthesis. Used in the preparation of the cytotoxic didemnin cyclopeptides and of the antineoplastic agent dolastatin 15.
ChEBI: (S)-2-hydroxy-3-methylbutyric acid is the S-enantiomer of 2-hydroxy-3-methylbutyric acid. It is used as a chiral building block for peptide synthesis. It has a role as a chiral reagent and a human metabolite. It is a conjugate acid of a (S)-2-hydroxy-3-methylbutyrate. It is an enantiomer of a (R)-2-hydroxy-3-methylbutyric acid.
