Description

Allyldichlorosilane is a highly reactive organosilicon compound characterized by its allyl and dichloro functional groups. This dual functionality makes it a versatile and valuable intermediate for introducing silicon-containing moieties into organic frameworks. It is primarily sought after by manufacturers in the specialty chemical and advanced materials sectors. Key applications include its use as a precursor for silicone polymers, coupling agents, and surface modification.

Application

• Silicone Intermediate: A key monomer for the synthesis of specialized silicone resins and elastomers with tailored properties.
• Surface Modification Agent: Used to functionalize inorganic surfaces like silica, glass, or metals, improving adhesion and compatibility in composite materials.
• Coupling Agent: Acts as a molecular bridge between organic polymers and inorganic fillers in advanced composites and coatings.
• Pharmaceutical & Agrochemical Synthesis: Serves as a building block for introducing silicon into bioactive molecules during research and development.
• Hydrosilylation Reactions: A crucial reagent in hydrosilylation processes to form carbon-silicon bonds, creating functional silanes.
• Crosslinking Agent: Employed in the production of crosslinked silicone networks for high-performance sealants and encapsulants.

Quality Control

Our Allyldichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee compliance with your technical requirements.

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 moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for extended stability.
