Mal-PEG-SCM

Product Overview

Heterobifunctional PEGs are polydisperse polyethylene glycol polymers featuring two different functional groups at opposite termini of the PEG chain. Depending on the product, the terminal functionalities may include amine, carboxylic acid, NHS ester, maleimide, thiol, azide, DBCO, aldehyde, or other reactive groups.

Their asymmetric structure enables sequential or orthogonal coupling with different molecules, providing greater control over conjugation strategies. Available in various molecular weight ranges and functional group combinations, Heterobifunctional PEGs are versatile building blocks for chemical synthesis, bioconjugation, and drug delivery research.

Applications

Heterobifunctional PEGs are widely used in directional conjugation, bioconjugation, click chemistry, PEGylation, and drug delivery research. Different terminal functional groups enable selective coupling with complementary reactive groups, making them useful for protein and peptide modification, antibody conjugation, targeted delivery systems, and the synthesis of functional PEG-based conjugates.
