Properties

Description

This substance features a 6-unit PEG chain with an acid group at one end and a t-butyl ester group at the other. The t-butyl ester can be used for protection and the acid group enables various coupling reactions. The hydrophilic PEG spacer increases solubility in aqueous solutions, and the t-butyl protected carboxyl group can be deprotected under acidic conditions.
