Description

Da-Peg-Nh2 is a heterobifunctional polyethylene glycol (PEG) derivative featuring a primary amine group at one terminus. This compound is a critical building block in bioconjugation and pharmaceutical development, enabling the creation of stable, water-soluble linkages between molecules. It is essential for researchers and manufacturers in the biopharmaceutical, diagnostics, and advanced materials sectors who require precise and reliable PEGylation reagents.

Application

• Bioconjugation reagent for attaching drugs, proteins, or peptides to nanoparticles, surfaces, or other biomolecules.
• Intermediate in the synthesis of antibody-drug conjugates (ADCs) and other targeted therapeutic constructs.
• Surface functionalization agent for modifying biomaterials, hydrogels, and diagnostic assay platforms.
• Crosslinker for the preparation of PEG-based networks and controlled-release drug delivery systems.
• Building block for synthesizing more complex heterobifunctional and multi-arm PEG derivatives.
• Tool in proteomics and biochemical research for labeling and purification purposes.
