Cas no 71989-43-0 (H-Thr(tBu)-OMe.HCl)

H-Thr(tBu)-OMe·HCl is a protected derivative of threonine, where the hydroxyl group is tert-butylated (tBu) and the carboxyl group is methyl-esterified (OMe). This compound is commonly used in peptide synthesis to prevent unwanted side reactions during coupling steps. The tert-butyl protection enhances stability under acidic conditions, while the methyl ester facilitates solubility in organic solvents. The hydrochloride (HCl) salt form improves handling and storage. This reagent is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase methods, offering controlled deprotection kinetics and compatibility with standard Fmoc/tBu strategies. Its high purity and consistent performance make it a reliable choice for complex peptide assembly.
