Description

Mpeg9-N3 is a functionalized polyethylene glycol derivative featuring a terminal azide group, enabling its use as a versatile linker in advanced bioconjugation and materials science. This compound is critical for researchers and manufacturers requiring precise, bio-orthogonal click chemistry reactions to modify surfaces, polymers, or biomolecules. It is particularly valuable for professionals in pharmaceutical development, nanotechnology, and diagnostic reagent formulation who need reliable, high-purity building blocks for creating sophisticated functional materials.

Application

• Bioconjugation and Protein PEGylation: Acts as a heterobifunctional linker for attaching polyethylene glycol (PEG) chains to proteins, peptides, or antibodies to improve solubility, stability, and pharmacokinetics.
• Click Chemistry Scaffold: The terminal azide group readily participates in copper-catalyzed or strain-promoted azide-alkyne cycloaddition (CuAAC/SPAAC) with alkynes for labeling, crosslinking, and polymer functionalization.
• Nanoparticle and Liposome Surface Modification: Used to functionalize the surface of drug delivery carriers (e.g., liposomes, polymeric nanoparticles) for targeted delivery and stealth properties.
• Hydrogel and Biomaterial Synthesis: Serves as a crosslinking agent or functional monomer in the creation of biocompatible hydrogels and scaffolds for tissue engineering and 3D cell culture.
• Diagnostic Assay Development: Employed to conjugate detection molecules (e.g., dyes, enzymes) to probes or solid supports in ELISA, lateral flow assays, and other diagnostic platforms.
• Polymer Chemistry: A key intermediate for synthesizing block copolymers, graft polymers, and other advanced polymeric architectures with tailored properties.
• Surface Plasmon Resonance (SPR) & Biosensor Fabrication: Facilitates the oriented immobilization of biomolecules onto sensor chips for real-time interaction analysis.
