Description

Bis(3-Trimethylsilylpropyl)Amine is a versatile organosilicon compound featuring a central amine group flanked by two trimethylsilylpropyl chains. This structure makes it a valuable intermediate and functionalizing agent, particularly as a silylating reagent and a precursor for advanced materials. It is essential for manufacturers and R&D teams in the pharmaceutical, agrochemical, and specialty polymer sectors who require precise surface modification or the introduction of silicon-containing functional groups. Its properties facilitate applications ranging from catalyst synthesis to the creation of hydrophobic coatings and silicone-based polymers.

Application

• Silylating Reagent: Used to introduce trimethylsilyl groups onto various substrates, protecting reactive sites like hydroxyls or amines during complex organic syntheses in pharmaceutical and agrochemical production.
• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to inorganic surfaces like silica, glass, or metals, enhancing performance in coatings, composites, and fillers.
• Polymer & Resin Intermediate: Serves as a monomer or cross-linking agent in the synthesis of specialty silicones, siloxane-based polymers, and high-performance resins with tailored thermal and mechanical properties.
• Catalyst & Ligand Synthesis: Acts as a precursor for creating nitrogen-containing ligands for transition metal catalysts used in homogeneous catalysis and fine chemical manufacturing.
• Adhesive & Sealant Formulations: Functions as an adhesion promoter and modifier in silicone-based adhesive and sealant systems, improving bonding to difficult substrates.
• Electronics & Semiconductor Industry: Employed in the passivation of surfaces and as a precursor in chemical vapor deposition (CVD) processes for thin-film applications.

Quality Control

Our Bis(3-Trimethylsilylpropyl)Amine is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or HPLC and identification by FT-IR and NMR spectroscopy. Certificates of Analysis (COA) detailing all specification parameters are provided with every shipment to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and oxidizing agents.
