Description

Iminobis(Dimethylchlorosilane) is a versatile organosilicon compound featuring two reactive chlorosilane groups linked by an imino bridge. This structure makes it a valuable key intermediate for synthesizing more complex silane coupling agents, silicone polymers, and surface-modifying materials. It is primarily sought by manufacturers in the silicone elastomer, adhesive, and specialty chemical industries for developing products with tailored properties.

Application

• Key Intermediate for Silane Coupling Agents: Serves as a precursor for synthesizing bifunctional aminosilanes used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Silicone Polymer Modification: Used to introduce branching points or functional groups into silicone chains, altering properties such as flexibility, crosslink density, and thermal stability.
• Surface Treatment Agent: Imparts hydrophobic or reactive surface properties to silica, fillers, and other substrates to enhance compatibility in composite materials.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of specialized organosilicon compounds for advanced applications.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new silicone-based materials and coatings.

Quality Control

Our production of Iminobis(Dimethylchlorosilane) adheres to stringent internal quality standards to ensure batch-to-batch consistency and reliability. Every lot is analyzed using advanced techniques like GC and NMR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong acids, and bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure maximum shelf life.
