Description

Tri(Amino-Peg3-Amide)-Amine is a specialized, multi-functional polyethylene glycol (PEG)-based amine linker with a branched, tri-armed structure. This compound matters for its unique ability to provide multiple reactive amine sites for conjugation, coupled with the solubility and biocompatibility benefits of PEG spacers. It is primarily needed by researchers and manufacturers in the pharmaceutical, bioconjugation, and advanced materials sectors for developing drug delivery systems, diagnostic probes, and functional polymers.

Application

• Bioconjugation & Drug Delivery: Serves as a key linker for attaching targeting ligands, dyes, or therapeutic payloads to nanoparticles, antibodies, or proteins.
• Polymer & Dendrimer Synthesis: Acts as a versatile branching core or functional monomer for creating PEGylated hydrogels, smart materials, and dendritic structures.
• Diagnostic Reagent Development: Used to functionalize surfaces and particles for immunoassays, biosensors, and imaging contrast agents.
• Peptide & Protein Modification: Facilitates site-specific PEGylation (PEG modification) to improve the stability, solubility, and pharmacokinetic profiles of biologics.
• Crosslinking Agent: Employed in the preparation of crosslinked networks for controlled release matrices and tissue engineering scaffolds.
• Surface Functionalization: Used to amine-functionalize gold nanoparticles, quantum dots, and other inorganic substrates for further bioconjugation.
