Description

Trichloro[(Z)-2-Butenyl]Silane CAS NO 49749-84-0 is a specialized organosilicon compound featuring a reactive trichlorosilyl group attached to a (Z)-2-butenyl (cis-crotyl) moiety. This unique structure makes it a valuable intermediate and precursor in advanced organic synthesis and materials science, where precise control over molecular architecture is critical. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for introducing silicon-containing functional groups.

Application

• Key Intermediate in Pharmaceutical Synthesis: Used to introduce silyl-protected functional groups or as a building block for active pharmaceutical ingredients (APIs).
• Agrochemical Product Development: Serves as a precursor in the synthesis of novel herbicides, fungicides, and plant growth regulators.
• Surface Modification and Coupling Agent: Functionalizes inorganic surfaces (e.g., silica, glass) or polymers to alter adhesion, wettability, and compatibility properties.
• Precursor for Silicone Chemistry: Acts as a starting material for the synthesis of custom polysiloxanes and silicone-based materials with specific chain architectures.
• Organic Synthesis Reagent: Employed in hydrosilylation reactions and as a source of the (Z)-2-butenyl group in cross-coupling and other metal-catalyzed transformations.
• Materials Science Research: Used in developing advanced hybrid organic-inorganic materials, coatings, and resins.

Quality Control

Our Trichloro[(Z)-2-Butenyl]Silane is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR analysis, to confirm identity, isomeric purity ((Z)-isomer content), and chemical purity. Certificates of Analysis (COA) detailing all relevant specifications are provided and available upon request to ensure traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C or as specified on the label. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept sealed under an inert atmosphere (argon or nitrogen) when not in use. Keep away from strong acids, bases, and oxidizing agents.
