Description

Di-n-Butylmethylchlorosilane is a versatile organosilicon compound, specifically a chlorosilane, widely used as a key reagent in organic synthesis and surface modification. Its primary value lies in its ability to act as a silylating agent, introducing the di-n-butylmethylsilyl protecting group or modifying surfaces with specific organic functionalities. This chemical is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and advanced materials sectors, where precise molecular construction and controlled surface properties are critical.

Application

• Silylating Agent in Organic Synthesis: Used to protect hydroxyl (-OH) groups in the synthesis of complex molecules like pharmaceuticals, natural products, and fine chemicals.
• Surface Modification of Inorganic Materials: Employed to functionalize silica, glass, or metal oxides, imparting hydrophobic or specific reactive properties for advanced composites and coatings.
• Intermediate for Silicone Polymers: Serves as a building block in the production of specialized silicone oils, resins, and elastomers with unique side-chain properties.
• Derivatization Reagent for Chromatography: Utilized to prepare volatile derivatives of polar compounds (e.g., alcohols, acids) for analysis by Gas Chromatography (GC) or GC-Mass Spectrometry (GC-MS).
• Coupling Agent in Adhesives and Sealants: Enhances the bond between organic polymers and inorganic fillers or substrates, improving mechanical performance.
• Reagent for Chemical Vapor Deposition (CVD): Acts as a precursor for depositing silicon-containing thin films in semiconductor and microelectronics fabrication.

Quality Control

Our Di-n-Butylmethylchlorosilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
