Description

1-(3-Chloroisobutyl)-1,1,3,3,3-Pentaethoxy-1,3-Disilapropane is a specialized organosilicon compound, specifically a chlorinated alkoxysilane, that serves as a critical building block in advanced material synthesis. Its molecular architecture, featuring both reactive chloro and ethoxy groups, makes it a versatile precursor for creating tailored siloxane networks and surface-modifying agents. This high-purity intermediate is essential for researchers and manufacturers in the silicone polymer, specialty coatings, and advanced adhesive industries who require precise control over material properties and cross-linking density.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce chlorinated alkyl side chains, enhancing specific properties like adhesion, compatibility, or reactivity in silicone elastomers and resins.
• Surface Treatment & Coupling Agent: Used to modify inorganic surfaces (e.g., glass, silica, metals) to improve hydrophobicity, promote adhesion of organic polymers, or create reactive sites for further chemical grafting.
• Synthesis of Hybrid Materials: Serves as a key precursor in sol-gel processes for developing organic-inorganic hybrid (OIH) coatings, films, and composites with customized mechanical and barrier properties.
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter and moisture-curable component in high-performance silicone and hybrid polymer sealants and adhesives.
• Pharmaceutical & Agro-chemical Intermediates: Utilized in the synthesis of more complex organosilicon molecules for potential application in drug delivery systems or as active ingredient carriers.
• Research & Development: A valuable reagent for academic and industrial R&D focused on novel organosilicon chemistry, dendritic polymers, and nanostructured materials.

Quality Control

Our production of 1-(3-Chloroisobutyl)-1,1,3,3,3-Pentaethoxy-1,3-Disilapropane adheres to a strict quality management system. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment. We support cGMP and ISO 9001 compliant manufacturing practices to meet the stringent requirements of our global B2B clientele.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (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 hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
