Description

Dab-Am-64, Polypropylenimine Tetrahexacontaamine Dendrimer, Generation 5.0 is a precisely defined, hyperbranched polymer with a high density of primary amine surface groups. This well-defined, nanoscale architecture is critical for applications requiring controlled surface functionalization and high ligand loading capacity. It is essential for researchers and manufacturers in advanced materials science, nanotechnology, and life sciences who require a consistent, high-purity dendritic scaffold.

Application

• Drug Delivery & Nanomedicine: Acts as a versatile nanocarrier for the encapsulation and targeted delivery of therapeutic agents, genes, or imaging contrast agents.
• Catalyst Support: Provides a high-surface-area, functional platform for immobilizing metal nanoparticles or organocatalysts, enhancing catalytic activity and selectivity.
• Polymer Additive & Crosslinker: Used to modify the properties of epoxy resins, polyurethanes, and other polymers, improving mechanical strength, thermal stability, or introducing new functionalities.
• Surface Modification & Coatings: Employed to create functional thin films or to modify material surfaces (e.g., sensors, membranes) with a dense layer of reactive amine groups.
• Complexation & Chelation Agent: Utilized for binding metal ions or small molecules in separation processes, environmental remediation, or as a component in diagnostic assays.
• Dendritic Nanoreactor: Serves as a confined, nanoscale environment for conducting chemical reactions or synthesizing nanoparticles with controlled size.

Quality Control

Every batch of our Polypropylenimine Dendrimer is synthesized and purified under controlled conditions to ensure structural integrity and batch-to-batch consistency. We employ advanced analytical techniques including Size Exclusion Chromatography (SEC/GPC), Nuclear Magnetic Resonance (NMR), and Mass Spectrometry for comprehensive characterization. A detailed Certificate of Analysis (COA) confirming purity, molecular weight, and amine group count is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. For long-term stability, storage at 2-8°C is recommended. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
