Description

Methyl-Tri-n-Butylsilane CAS NO 995-43-7 is a versatile organosilicon compound, a trialkylsilane derivative valued for its role as a key intermediate and functional reagent in advanced chemical synthesis. Its primary commercial significance lies in its ability to act as a silylating agent and a precursor for modifying surfaces and polymers, imparting specific hydrophobic or release properties. This product is essential for R&D laboratories and industrial manufacturers in the silicone, pharmaceutical, and specialty materials sectors seeking to develop innovative formulations and high-performance materials.

Application

• Silylation Reagent: Used in organic synthesis to introduce the silyl protecting group for sensitive functional groups like alcohols and amines.
• Surface Modification: Employed to hydrophobize inorganic surfaces such as silica, glass, or metals, enhancing water repellency and compatibility.
• Polymer & Silicone Intermediate: Serves as a building block or cross-linking agent in the production of modified silicones and specialty polymers.
• Pharmaceutical Intermediate: Acts as a key synthetic intermediate in the development of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Adhesion Promoter: Used in formulations to improve the adhesion between organic polymers and inorganic substrates.
• Lubricant & Release Agent Additive: Incorporated into formulations to provide lubricating or mold-release characteristics.

Quality Control

Our Methyl-Tri-n-Butylsilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC (Gas Chromatography) for purity and identity confirmation via FTIR (Fourier-Transform Infrared Spectroscopy), to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting all critical quality parameters are provided and available upon request to support your quality assurance protocols.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
