TSTU (Cat No.:R028787) is a versatile chemical compound commonly used as a coupling reagent in peptide synthesis. It contains a triazine ring and three pyridyl groups, which facilitate the activation of carboxylic acids to form amides in the presence of amines. TSTU is particularly useful in solid-phase peptide synthesis, where it helps improve reaction efficiency and yields by minimizing side reactions. It is favored for its ability to promote reactions under mild conditions and is widely employed in both laboratory research and pharmaceutical production for peptide and protein synthesis.
