Used primarily in peptide synthesis, this compound serves as a protected form of allo-isoleucine. It helps in the stepwise construction of peptides by preventing unwanted reactions at the amino group. The Boc (tert-butoxycarbonyl) group is easily removed under acidic conditions, allowing for further peptide chain elongation. This makes it valuable in the production of custom peptides for research, pharmaceuticals, and biotechnology applications. Its role is crucial in ensuring the accuracy and efficiency of peptide synthesis processes.
