TSTU Usage And Synthesis
Chemical PropertiesWhite crystalline
Usespeptide coupling reagent converts carboxylates to N-succinimidyl active esters
UsesReagent for the clean in-situ formation of N-succinimidyl active esters
UsesTSTU is used as a peptide coupling reagent in solvent systems.
General DescriptionN,N,N′,N′-Tetramethyl-O-(N-succinimidyl)uronium tetrafluoroborate is commonly used for the conversion of carboxylic acid into the corresponding N-hydroxysuccinimidyl (NHS) ester.
