Description

7-Octenyldimethylchlorosilane is a highly reactive organosilicon compound, specifically a chlorosilane with a terminal alkene group, making it a versatile bifunctional reagent. Its primary value lies in its dual functionality, serving as a key intermediate for introducing hydrophobic, cross-linkable, or surface-modifying groups in advanced materials. This product is essential for manufacturers in the silicone polymer, specialty chemical, and surface treatment industries seeking to create custom silane coupling agents, functionalized polymers, or hydrophobic coatings.

Application

• Silane Coupling Agent Precursor: Acts as a key intermediate for synthesizing custom silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, or minerals.
• Hydrophobic Surface Modification: Used to functionalize silica, nanoparticles, or other substrates to impart water-repellent properties for coatings, fillers, and composites.
• Silicone Polymer Cross-linking: The chlorosilane group enables chain extension or cross-linking in silicone resins, while the octenyl group can participate in hydrosilylation or other addition reactions for property modification.
• Organic Synthesis Intermediate: Serves as a protected or functionalized building block in pharmaceutical and agrochemical synthesis, leveraging the reactivity of both the Si-Cl and alkene moieties.
• Release Coating Formulations: A component in formulations for creating non-stick or easy-release coatings on papers, films, and industrial surfaces.
• Adhesive & Sealant Additive: Incorporated to enhance the moisture resistance, durability, and adhesion properties of high-performance adhesives and sealants.

Quality Control

Our 7-Octenyldimethylchlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting requirements of advanced material synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request, providing full traceability and quality assurance for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to maximize stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and oxidizing agents.
