Cas no 104944-18-5 (H-D-Val-OtBu.HCl)

H-D-Val-OtBu·HCl is a protected amino acid derivative widely used in peptide synthesis. The compound features a tert-butyl ester (OtBu) group, which provides stability under acidic conditions, and a hydrochloride (HCl) salt form for enhanced solubility and handling. The valine backbone is chiral, ensuring stereochemical integrity in peptide chain assembly. This reagent is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase methods, where its orthogonal protection strategy allows selective deprotection. Its high purity and consistent performance make it a reliable choice for constructing complex peptides, especially in pharmaceutical research and bioconjugation applications.
