Cat No.

CEGZ-6913

Description

3-[2-(2-Aminoethoxy)ethoxy]propionic acid is a short, monodisperse polyethylene glycol linker bearing a primary amino group at one end and a carboxylic acid at the other. The two ethylene oxide units provide a defined, hydrophilic spacer of fixed length.

Applications

Used as a hydrophilic spacer and linker in peptide synthesis, bioconjugation, drug delivery research, and the preparation of PEGylated peptides and small-molecule conjugates.

Product Overview

Heterobifunctional PEG linkers of this type are standard tools for introducing hydrophilic spacing between a peptide or small molecule and a conjugation partner. The terminal amino and carboxyl groups allow sequential amide-bond formation on either end of the spacer.
