Description

Chloro-Methyl-Propyl-Silane is a versatile organosilicon compound, specifically a chlorosilane, widely used as a key intermediate in organic synthesis and surface modification. Its primary value lies in its ability to introduce functional silane groups, enabling the creation of specialized coatings, adhesives, and advanced materials with tailored properties. This product is essential for manufacturers and R&D teams in the silicone polymer, pharmaceutical, and specialty chemical industries seeking to develop innovative products with enhanced performance characteristics.

Application

• As a crucial silane coupling agent for improving adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Key intermediate in organic synthesis for the production of more complex functionalized silanes and silicone derivatives.
• Used in the manufacture of silicone resins and polymers, contributing to properties like water repellency and thermal stability.
• Surface treatment agent for fillers and reinforcements (e.g., silica, glass fibers) in composite materials to enhance dispersion and mechanical strength.
• Precursor for hydrophobic coatings applied to construction materials, textiles, and electronic components.
• Employed in pharmaceutical research and fine chemical synthesis as a building block for novel compounds.
• Used in the formulation of sealants, adhesives, and elastomers to modify cross-linking behavior and final material properties.

Quality Control

Our Chloro-Methyl-Propyl-Silane is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including gas chromatography (GC), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

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