O-tert-Butyl-L-threonine (H-Thr(tBu)-OH) is a protected form of L-threonine commonly used in solid-phase peptide synthesis. It features a tert-butyl group that shields the hydroxyl side chain, preventing unwanted side reactions during coupling. This derivative ensures high purity and stability under standard peptide synthesis conditions.
