Description

3-Acetoxypropyl Methyl Dichlorosilane is a specialized organosilicon compound that serves as a key intermediate in the synthesis of functional silanes and silicone polymers. Its bifunctional structure, featuring both reactive chlorosilane and acetoxy groups, makes it a versatile building block for introducing specific organic functionalities onto silicon-based backbones. This chemical is essential for manufacturers in the silicone, adhesives, and specialty materials industries seeking to develop products with tailored surface properties, crosslinking capabilities, or adhesion promoters.

Application

• Silicone Polymer Modification: Used as a functional monomer or crosslinking agent in the production of specialty silicone resins, elastomers, and sealants.
• Surface Treatment Agent: Acts as a coupling agent for surface modification of inorganic materials like glass, silica, and metals to improve adhesion with organic polymers.
• Adhesive & Sealant Formulations: Imparts improved bonding characteristics and moisture-curing properties in high-performance industrial adhesives and sealants.
• Intermediate for Silane Synthesis: Serves as a critical precursor for the synthesis of other functional silanes, such as alkoxy or amino silanes, through substitution reactions.
• Hydrophobic Coatings: A key ingredient in formulations for creating water-repellent and protective coatings on various substrates.
• Pharmaceutical & Agro-chemical Intermediates: Employed in the synthesis of more complex organosilicon molecules for specialized applications in life sciences.

Quality Control

Our production of 3-Acetoxypropyl Methyl Dichlorosilane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to meet precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, and we support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 25°C. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents. Observe all local regulations for the storage of reactive chlorosilanes.
