Description

1,4-Bis(dimethylchlorosilyl)benzene is a high-purity organosilicon compound, specifically a bifunctional chlorosilane derivative, serving as a critical building block in advanced material synthesis. Its core value lies in its dual reactive chlorosilyl groups attached to a rigid benzene core, enabling the creation of novel polymers and hybrid materials with tailored properties. This product is essential for R&D and production teams in the specialty chemicals, advanced polymers, and electronics materials sectors seeking to develop next-generation silicones and silicon-based polymers.

Application

• Silicone Polymer Synthesis: A key monomer for the production of high-performance, heat-resistant silicone resins and elastomers.
• Hybrid Organic-Inorganic Materials: Used as a coupling agent or precursor for sol-gel processes to create advanced coatings, adhesives, and composites.
• Pharmaceutical & Agro-Intermediates: Serves as a versatile synthetic intermediate for introducing silicon-containing functional groups into complex molecules.
• Electronics & Semiconductor Materials: Employed in the development of low-k dielectric materials, passivation layers, and other silicon-based electronic components.
• Surface Modification: Used to functionalize silica, glass, or other inorganic surfaces to alter their chemical and physical properties.
• Crosslinking Agent: Acts as an efficient crosslinker in polymer systems to enhance thermal stability and mechanical strength.

Quality Control

Our 1,4-Bis(dimethylchlorosilyl)benzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

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