Description

Starburst (Pamam) Dendrimer, Generation 9, 5 Wt. % Solution in Methyl Alcohol is a precisely engineered, monodisperse hyperbranched polymer solution. This high-generation dendrimer is critical for applications requiring a well-defined, nanoscale scaffold with a high density of surface functional groups. It is essential for researchers and product developers in advanced material science, nanotechnology, and life sciences. The product is supplied as a 5% by weight solution in methanol for convenient handling and integration into various formulations.

Application

• Drug Delivery & Nanomedicine: As a core component for constructing targeted drug delivery systems, gene vectors, and contrast agents due to its biocompatibility and modifiable surface.
• Catalyst Support: Serving as a nanoscale platform for immobilizing metal catalysts, enhancing catalytic activity and selectivity in organic synthesis.
• Sensor & Diagnostic Platforms: Functionalizing surfaces for biosensors and diagnostic assays by attaching recognition molecules (e.g., antibodies, DNA) to its numerous terminal amines.
• Advanced Material Synthesis: Acting as a building block or cross-linker for creating nanocomposites, hydrogels, and thin films with tailored properties.
• Surface Modification: Modifying material surfaces (e.g., polymers, metals) to alter wettability, adhesion, or to introduce specific chemical functionalities.
• Research & Development: A fundamental tool in academic and industrial R&D for exploring supramolecular chemistry, host-guest interactions, and nanoscale assembly processes.

Quality Control

Our dendrimer solutions are produced under strict quality control protocols to ensure batch-to-batch consistency and purity. Each lot is characterized using advanced analytical techniques including size-exclusion chromatography (SEC/GPC), nuclear magnetic resonance (NMR), and mass spectrometry to confirm generation, structure, and concentration. Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

Storage

Preserve in the original tightly closed container, protected from light. Store at 2-8°C (refrigerated) to maximize shelf-life stability. Due to the highly volatile nature of the methanol solvent, ensure containers are securely sealed and stored in a well-ventilated area away from heat and ignition sources. Allow the solution to reach room temperature before opening to prevent condensation.
