Cas no 139937-99-8 (2-{(tert-butoxy)carbonylamino}-2-ethylbutanoic acid)

2-{(tert-Butoxy)carbonylamino}-2-ethylbutanoic acid is a protected amino acid derivative featuring a tert-butoxycarbonyl (Boc) group, which enhances stability and facilitates selective deprotection in peptide synthesis. The ethylbutanoic acid backbone provides steric bulk, influencing conformational control in intermediate structures. The Boc group is widely recognized for its compatibility with standard solid-phase peptide synthesis (SPPS) protocols, ensuring minimal side reactions. This compound is particularly useful in medicinal chemistry and bioconjugation, where controlled amine reactivity is required. Its crystalline form allows for straightforward purification and handling. The combination of steric hindrance and orthogonal protection makes it a valuable building block for complex organic and peptide-based applications.
