Description

tert-Butyl-n-propyldimethoxysilane is a specialized organosilicon compound, a dialkoxysilane derivative, designed for advanced material synthesis and surface modification. Its molecular structure, featuring both tert-butyl and n-propyl groups, offers a unique balance of steric bulk and reactivity, making it a valuable precursor for creating tailored silane coupling agents and protective coatings. This chemical is essential for R&D and production in industries requiring precise control over material interfaces and hydrophobicity.

Application

• Silane Coupling Agent Precursor: A key intermediate for synthesizing custom silane coupling agents used to enhance adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Surface Modification & Hydrophobization: Used to impart water-repellent (hydrophobic) properties to silica, nanoparticles, and other fillers, improving their compatibility and dispersion in polymer matrices.
• Protective Coating Formulations: Serves as a cross-linking agent or modifying monomer in the development of high-performance silicone-based protective coatings and sealants.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of silicon-containing bioactive molecules and active ingredients, leveraging silicon's ability to modulate pharmacokinetic properties.
• Advanced Material Research: Utilized in academic and industrial R&D for creating novel hybrid organic-inorganic materials (ORMOSILs), sorbents, and catalysts.
• Adhesive & Composite Enhancement: Modifies filler surfaces in composite materials to improve mechanical strength, thermal stability, and moisture resistance.

Quality Control

Our tert-Butyl-n-propyldimethoxysilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment 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). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain purity. Keep away from heat, sparks, and open flames.
