Description

Di-iso-Propylaminosilane is a specialized organosilicon compound featuring a reactive silane group bonded to a diisopropylamine moiety. This structure makes it a valuable precursor and intermediate in advanced materials science, particularly for surface modification and controlled deposition processes. It is essential for manufacturers and R&D facilities in the semiconductor, nanotechnology, and specialty chemical sectors seeking to engineer specific surface properties or create novel silicon-based materials.

Application

• Semiconductor Manufacturing: Used as a precursor for Atomic Layer Deposition (ALD) or Chemical Vapor Deposition (CVD) to deposit silicon nitride (SiN) or silicon carbonitride (SiCN) thin films.
• Surface Functionalization: Acts as a coupling agent to modify the surface of inorganic materials like silica, glass, or metals, introducing amine-reactive sites for further chemical grafting.
• Polymer Synthesis: Serves as a monomer or cross-linking agent in the synthesis of specialized polysilazanes or silicon-containing polymers.
• Nanoparticle Capping: Employed to passivate and stabilize the surface of silicon or other semiconductor nanoparticles, controlling their reactivity and dispersion.
• Adhesive & Sealant Formulations: Functions as an adhesion promoter in high-performance silicone or epoxy-based systems, improving bond strength to difficult substrates.
• Pharmaceutical Intermediates: Utilized in the synthesis of complex molecules where a protected or functionalized silicon group is required.

Quality Control

Our Di-iso-Propylaminosilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation.
