Description

(E)-2-Butenyltrichlorosilane is a highly reactive organosilicon compound characterized by its trichlorosilyl group attached to a trans-butene moiety. This structure makes it a valuable intermediate for introducing the (E)-2-butenyl functional group into silicon-based materials, enabling precise surface modification and polymer cross-linking. It is primarily sought after by manufacturers in the silicone polymer, specialty chemical, and advanced materials sectors for developing tailored adhesion promoters, hydrophobic coatings, and release agents.

Application

• Silicone Intermediate: A key building block for synthesizing custom silicone oils, resins, and elastomers with specific organic side chains.
• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to alter wettability and improve adhesion for coatings and composites.
• Coupling Agent: Acts as a molecular bridge to enhance the interface between organic polymers and inorganic fillers in composite materials.
• Adhesion Promoter: Incorporated into primers and sealants to improve bonding to difficult substrates.
• Hydrophobic Coating Precursor: Employed in the formulation of water-repellent and anti-corrosive surface treatments.
• Release Agent Synthesis: Used to manufacture silicone-based release coatings for papers, films, and molds.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a specialized synthon in the production of more complex organosilicon molecules for life science applications.
• Research & Development: Utilized in academic and industrial R&D for exploring new organosilicon chemistry and material properties.

Quality Control

Our (E)-2-Butenyltrichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and functional group verification, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
