Description

Dicyclohexyldichlorosilane CAS NO 18035-74-0 is a highly reactive organosilicon compound primarily used as a versatile building block in organosilicon chemistry. Its value lies in its ability to introduce the dicyclohexylsilyl group, a bulky hydrophobic moiety, into target molecules, modifying their surface properties and reactivity. This chemical is essential for manufacturers and R&D teams in the silicone polymer, specialty chemical, and advanced materials sectors seeking to develop products with tailored characteristics.

Application

• Silicone Intermediate: A key precursor for synthesizing specialized silicone oils, resins, and elastomers with enhanced thermal stability and hydrophobicity.
• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces to impart water-repellent (hydrophobic) properties.
• Pharmaceutical & Agrochemistry Intermediates: Serves as a protecting group or a structural component in the synthesis of complex bioactive molecules.
• Adhesion Promoter: Incorporated into primers and coupling agents to improve the bond between organic polymers and inorganic substrates.
• Catalyst & Ligand Synthesis: Employed in the preparation of novel organosilicon ligands for transition metal catalysis.
• Research & Development: A valuable reagent in academic and industrial labs for exploring new organosilicon compounds and materials science applications.

Quality Control

Our Dicyclohexyldichlorosilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (GC), purity verification, and impurity profiling, to ensure it meets exacting standards for consistency and performance. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, strong bases, and oxidizing agents.
