Description

Tri-n-Hexylchlorosilane is a high-purity organosilicon compound, specifically a chlorosilane, widely used as a key intermediate in organic synthesis and materials science. Its primary value lies in its ability to act as a versatile silylating agent, introducing the tri-n-hexylsilyl protecting group to modify the properties of target molecules. This product is essential for research and development laboratories, as well as industrial-scale production in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to create advanced materials with tailored functionalities.

Application

• Silylating Agent: Used as a protecting group reagent in the synthesis of complex organic molecules, particularly in pharmaceutical intermediates.
• Surface Modification: Employed to functionalize silica, glass, and other inorganic surfaces to impart hydrophobic properties.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of specialized silicone polymers and resins.
• Chemical Intermediate: A crucial precursor for the synthesis of other organosilicon compounds, such as silanols and alkoxysilanes.
• Catalyst and Ligand Synthesis: Used in the preparation of ligands for metal catalysts used in homogeneous catalysis.
• Adhesion Promotion: Can be formulated into primers to improve the adhesion of sealants and coatings to various substrates.

Quality Control

Our Tri-n-Hexylchlorosilane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, oxidizers, and moisture. Due to its hygroscopic and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain product integrity. Recommended storage temperature is 2-8°C.
