Catalogue Number852044
Replaces04-12-1089
Brand Family Novabiochem®
Alternate Names
  • N-α-Fmoc-N-β-trityl-L-asparagine
Background InformationFmoc-Asn(Trt)-OH has good solubility properties in most organic solvents, and its use has been shown to result in significantly purer peptides than other derivatives used for the introduction of Asn [1, 2]. Coupling can be performed by standard procedures. The trityl group is normally removed by 95% TFA in 1-3 hours, with no alkylation of Trp residues. When Asn(Trt) is the N-terminal residue, the reaction time may need to be extended to ensure complete deprotection [3].

The product number for this product was previously 04-12-1089.
