Cas no 62-57-7 (2-amino-2-methylpropanoic acid)
2-Amino-2-methylpropanoic acid, also known as α-aminoisobutyric acid (AIB), is a non-proteinogenic amino acid with a branched alkyl side chain. Its unique structure, featuring a quaternary alpha carbon, confers enhanced steric hindrance and metabolic stability compared to linear amino acids. This compound is widely utilized in peptide synthesis to modify conformational properties and improve resistance to enzymatic degradation. It also serves as a valuable intermediate in pharmaceutical research, particularly in the development of peptidomimetics and bioactive compounds. Due to its high purity and consistent performance, 2-amino-2-methylpropanoic acid is a preferred choice for applications requiring precise structural control and stability.
