Hydroxy-PEG2-CH2CO2t-Bu

Hydroxy-PEG2-CH2CO2tBu is a PEG linker containing a hydroxyl group with a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

Hydroxy-PEG2-CH2CO2tBu was a useful reagent in the study for potentiator-corrector agonist of cystic fibrosis mutant protein ΔF508-CFTR preparation.
