Tos-PEG7-t-butyl ester Chemical Properties,Usage,Production

Description

Tos-PEG7-t-Butyl ester is a PEG linker containing a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The tosyl group is a very good leaving group for nucleophilic substitution reactions.

Uses

Tos-PEG6-C2-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
