Application:

TSTU (CAS: 105832-38-0), peptide coupling reagent converts carboxylates to N-succinimidyl active esters. TSTU is commonly used for the conversion of carboxylic acid into the corresponding N-hydroxysuccinimidyl (NHS) ester. Ideal for the conversion of dyes and PEG building blocks to the corresponding active esters for coupling in aqueous media.
