Z-2-Aminoisobutyric acid

Z-2-Aminoisobutyric acid contains a 2-aminoisobutyric acid backbone bearing a Z (benzyloxycarbonyl, Cbz) protecting group on the amino functionality, classifying it as a protected amino acid derivative rather than a free amino acid. The molecule features a carboxyl group and a Cbz-protected primary amine, with the side chain being a branched isobutyl-like substituent that provides hydrophobic character and steric bulk; stereochemistry is not specified in the product name. Z-2-Aminoisobutyric acid is used as a precursor for incorporating the protected amino acid unit into peptide synthesis workflows and as a chemically defined building block for preparing amino acid derivatives where controlled amine reactivity is required.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
