General Description

TSTU supply - 105832-38-0 |Efficient peptide coupling reagent for spot supply

TSTU (CAS:105832-38-0) is a coupling reagent used to form amides via a reactive N-hydroxysuccinimidyl ester. TSTU finds application in the post-synthetic chemical derivatisation of cyanine and rhodamine dyes to be used as fluorescent labels and in the synthesis of the N-succinimidyl 4-[18F]fluorobenzoate ([18F]SFB) to form conjugated to be used as PET tracers.


TSTU forms activated succinimidyl esters that are stable in water.  TSTU is useful for conjugating peptides and labeles to water soluble proteins.
