Fmoc-Gln(Trt)-OH

C₃₉H₃₄N₂O₅

610.70

MFCD00077056

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.

The product number for this product was previously 04-12-1090.
