Beschreibung

General description

N,N,N′,N′-Tetramethyl-O-(N-succinimidyl)uronium hexafluorophosphate can be used to prepare N-succinimidyl 4-[¹⁸F]fluorobenzoate ([¹⁸F]-SFB), a prosthetic group for the fluorination of biomolecules for PET imaging.

Application

Reactant for:
Synthesis of liposomal contrast agents for magnetic resonance imaging
Synthesis of thiol-reactive Cy5 derivatives
Synthesis of protein labeling molecules

Other Notes

Coupling reagent for peptide synthesis and the formation of other amides. Even in aqueous solution yields are excellent
