Description

Acetoxyethyldimethylchlorosilane is a versatile organosilicon compound that serves as a key intermediate in the synthesis of functionalized silanes and silicone polymers. Its bifunctional nature, featuring both a reactive chlorosilane group and an acetoxyethyl moiety, makes it a valuable building block for introducing specific organic functionality to silicon-based materials. This compound is particularly sought after by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for creating custom silane coupling agents, surface modifiers, and specialized silicone precursors.

Application

• Silane Coupling Agent Precursor: Used to synthesize custom coupling agents for improving adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Surface Modification: Imparts specific hydrophobic or functional properties to silica, nanoparticles, and other fillers for composite material enhancement.
• Pharmaceutical Intermediates: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs) and drug delivery system components that require silicon-based functional groups.
• Agrochemical Synthesis: Employed in the manufacture of silicon-containing pesticides, herbicides, and plant growth regulators.
• Polymer & Resin Modification: Used to introduce cross-linking sites or modify the properties of silicone resins, rubbers, and specialty polymers.
• Protective Group in Organic Synthesis: The acetoxyethyl group can act as a protecting group for alcohols or other functionalities during complex multi-step syntheses.
• Adhesive & Sealant Formulations: Incorporated to enhance the moisture-curing characteristics and adhesion profile of silicone-based adhesives and sealants.
• Research & Development: A valuable reagent for academic and industrial R&D in organosilicon chemistry and material science.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade. This product is hygroscopic (moisture-sensitive) and highly volatile. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and oxidation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and oxidizing agents.
