Description

Pss-(3-(2-Aminoethyl)Amino)Propyl-Hepta& CAS NO 444315-16-6 is a specialized organosilane compound featuring a branched heptaisobutyl-POSS (Polyhedral Oligomeric Silsesquioxane) cage core functionalized with a propyl linker and a diamine (ethylenediamine) terminal group. This unique hybrid structure combines the robust, thermally stable inorganic silica-like cage with the reactive organic amine functionality, making it a critical building block for advanced material synthesis. It is essential for researchers and manufacturers developing high-performance polymers, nanocomposites, and surface modification agents. Target industries include specialty chemicals, advanced materials, electronics, and coatings where enhanced thermal stability, mechanical properties, and precise surface functionalization are required.

Application

• Advanced Polymer & Nanocomposite Precursor: Serves as a reactive monomer or cross-linking agent to incorporate POSS cages into polymer backbones (e.g., epoxies, polyimides, polyurethanes) to dramatically improve thermal stability, mechanical strength, and reduce flammability.
• Surface Modification & Coupling Agent: The primary amine groups enable covalent bonding to various substrates (glass, metals, fillers like silica) and polymers, improving adhesion, dispersion, and interfacial properties in composite materials.
• Hybrid Material Synthesis: Used in sol-gel processes to create organic-inorganic hybrid (OIH) materials with tailored porosity, functionality, and optical properties for sensors, catalysts, and separation membranes.
• Electronics & Semiconductor Materials: Employed in the formulation of low-k dielectric materials, protective coatings, and encapsulants that require high thermal endurance and low moisture uptake.
• Specialty Additives for Coatings & Adhesives: Imparts scratch resistance, weatherability, and enhanced bonding when formulated into high-performance coatings, inks, and adhesive systems.
• Bioconjugation & Drug Delivery Platform: The reactive amine handle allows for attachment of biomolecules (peptides, antibodies) or drugs, creating novel nanocarriers or diagnostic platforms in biomedical research.
• Catalyst & Ligand Support: The POSS core provides a stable, high-surface-area platform for immobilizing metal catalysts or complex ligands, facilitating recyclable catalytic systems.

Quality Control

Our production of Pss-(3-(2-Aminoethyl)Amino)Propyl-Hepta& CAS NO 444315-16-6 adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot undergoes comprehensive analysis, including structural verification and purity assessment. Certificates of Analysis (COA) detailing specific test results are provided with every shipment. We support custom synthesis and can tailor specifications to meet specific project requirements, including compliance with relevant material safety and handling standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture absorption. Keep away from strong acids and oxidizing agents.
