| Molecular Formula: | C31H30N2O6 |
| Molecular Weight: | 526.6 |
| The use of this protected tryptophan derivative overcomes most of the problems associated with the preparation of Trp containing-peptides by Fmoc SPPS. Cleavage with TFA generates an N-in-carboxy indole which protects the Trp from alkylation and sulfonation. The N-in-carboxy group is removed under aqueous conditions during normal work-up of the peptide. References 1. P. White in “Peptides, Chemistry & Biology, Proc. 12th American Peptide Symposium”, J.
