Cas no 32991-17-6 ((tert-Butoxycarbonyl)-L-leucylglycine)

(tert-Butoxycarbonyl)-L-leucylglycine is a protected dipeptide derivative consisting of L-leucine and glycine, with a Boc (tert-butoxycarbonyl) protecting group on the N-terminus. This compound is commonly used in peptide synthesis, where the Boc group provides stability under basic conditions and can be selectively removed under acidic conditions. The presence of L-leucine enhances hydrophobicity, while glycine contributes flexibility to peptide chains, making this derivative valuable in designing bioactive peptides or modified structures. Its high purity and well-defined protection strategy facilitate efficient solid-phase or solution-phase peptide coupling. This reagent is particularly useful in medicinal chemistry and biochemical research for constructing complex peptide sequences.
