Description

Dab-Am-4, Polypropylenimine Tetraamine Dendrimer, Generation 1.0 is a well-defined, low-generation polyamine dendrimer with a tetra-branched, star-shaped architecture. This precise molecular structure makes it a versatile and highly functional building block for creating advanced materials with tailored surface properties. It is particularly valuable for researchers and manufacturers in the fields of nanotechnology, pharmaceuticals, and specialty polymers who require a multifunctional amine core for cross-linking, surface modification, or as a scaffold for drug delivery systems.

Application

• Cross-linking Agent: Used as a high-functionality amine hardener for epoxy resins, polyurethanes, and other polymers to enhance thermal and mechanical properties.
• Nanocarrier Synthesis: Serves as a core scaffold for constructing dendrimer-based drug delivery systems, enabling controlled drug loading and release.
• Surface Modification: Applied to coat and functionalize nanoparticles (e.g., gold, silica) or solid surfaces to introduce amine groups for subsequent bioconjugation or adhesion promotion.
• Catalyst Support: Utilized as a ligand or support framework for immobilizing metal catalysts in homogeneous and heterogeneous catalysis.
• Chelating Agent: Employed in water treatment or metal recovery processes due to its multiple amine sites capable of binding metal ions.
• Gene Transfection: Investigated as a cationic polymer for complexing and delivering nucleic acids (DNA, siRNA) in biomedical research.
• Sensor Development: Acts as a platform for attaching fluorescent or receptor moieties to create chemical or biological sensors.
• Adhesive Formulation: Incorporated into adhesive systems to improve bonding strength and chemical resistance.

Quality Control

Our Dab-Am-4 Dendrimer is manufactured under strict quality protocols. Each batch undergoes comprehensive analytical testing, including NMR (¹H and ¹³C) for structural confirmation, HPLC for purity assessment, and titration for amine value determination. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation and absorption of moisture and carbon dioxide.
