TSTU Usage And Synthesis

Chemical Properties

White crystalline

Uses

peptide coupling reagent converts carboxylates to N-succinimidyl active esters

Uses

Reagent for the clean in-situ formation of N-succinimidyl active esters

Uses

TSTU is used as a peptide coupling reagent in solvent systems.

General Description

N,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.
