Descripción

Descripción general

High purity Fmoc-protected amino acid for research and process production of peptides, with very low levels of dipeptide, free-amino acids and acetic acid impurities.
Fmoc-Gln(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 Gln ^[1]. Coupling can be performed by standard procedures. The trityl-protecting group is normally removed by 95% TFA in 1-3 hours, with no alkylation of Trp.
