Overview
S-acetyl-PEG6-t-butyl ester is a PEG derivative containing a sulfur acetyl group and a t-butyl ester. The sulfur acetyl group can be deprotected to form a thiol group. The t-butyl ester can be removed under acidic conditions. The hydrophilic PEG linker increases the water solubility of compounds in aqueous media.
