Cas no 52498-32-5 (Boc-N-Methyl-L-isoleucine)

Boc-N-Methyl-L-isoleucine is a protected derivative of L-isoleucine, featuring a Boc (tert-butoxycarbonyl) group at the N-terminus and a methyl substitution on the amide nitrogen. This compound is widely used in peptide synthesis, where the Boc group serves as a temporary protecting group for the amino function, enabling selective deprotection under mild acidic conditions. The N-methylation enhances conformational flexibility and metabolic stability in peptide analogs. Its high purity and well-defined stereochemistry make it valuable for medicinal chemistry and drug development. The product is typically supplied as a white crystalline solid, ensuring consistent performance in solid-phase and solution-phase peptide synthesis applications.
