General description
2-Aminoisobutyric acid also known as α-aminobutyric acid, is an amino acid used in solution-phase peptide synthesis. It is a desirable building block for peptides because of its strong tendency to cause the peptide to form a helical shape.
Application
2-Aminoisobutyric acid can be used to synthesize self-assembled polypeptide nanoparticles. Incorporation of this compound into the peptide chain can prevent undesired reactions since it is di-α-substituted, and inert to C−H abstraction.

Amine-containing mixed-matrix membranes incorporated with amino-functionalized multi-walled carbon nanotubes (AF-MWNTs) were synthesized for CO2/H2 separation based on the facilitated transport mechanism. AF-MWNTs were chosen primarily as the mechanical reinforcing filler to enhance the membrane stability. At 107 °C and 0.2-MPa
