Description

Cyclooctyltrichlorosilane is a highly reactive organosilicon compound used as a key intermediate in the synthesis of advanced materials. Its value lies in its ability to introduce the cyclooctyl functional group onto surfaces or into polymer chains, imparting specific hydrophobic and chemical resistance properties. This product is essential for manufacturers in the semiconductor, specialty polymer, and surface coating industries seeking to develop high-performance materials.

Application

• Surface Modification Agent: Used as a silylating reagent to functionalize silica, glass, and other metal oxide surfaces for improved hydrophobicity and adhesion.
• Precursor for Silicone Polymers: Serves as a monomer or cross-linking agent in the synthesis of specialty cyclooctyl-substituted polysiloxanes and silicone resins.
• Semiconductor Manufacturing: Employed in chemical vapor deposition (CVD) or atomic layer deposition (ALD) processes to create thin films and dielectric layers.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic substrates in composite materials and coatings.
• Pharmaceutical Intermediate: Utilized in the synthesis of complex molecules and drug candidates where silicon incorporation is required.
• Research & Development: A valuable building block in organometallic chemistry and materials science research for creating novel architectures.

Quality Control

Our Cyclooctyltrichlorosilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area, away from heat and incompatible materials. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C.
