Description

Methylethylchlorosilane is a versatile organosilicon compound, primarily valued as a key intermediate in the synthesis of silicone polymers and functional silanes. Its reactive chlorosilane group makes it essential for introducing methylethylsiloxy units into various silicone backbones, modifying properties like flexibility, hydrophobicity, and thermal stability. This chemical is critical for manufacturers in the silicone elastomer, resin, and specialty coatings industries, as well as for R&D laboratories developing advanced materials.

Application

• Silicone Intermediate: A fundamental building block for the production of methylethyl silicone oils, greases, and high-performance elastomers.
• Surface Modification: Used to synthesize coupling agents for improving adhesion between organic polymers and inorganic surfaces like glass or minerals.
• Pharmaceutical & Agrochemical Synthesis: Serves as a protecting group or synthetic intermediate in the manufacture of complex active ingredients.
• Hydrophobic Coatings: A precursor for creating water-repellent treatments for textiles, construction materials, and electronic components.
• Crosslinking Agent: Employed in room-temperature vulcanizing (RTV) silicone rubbers and sealants.
• Research & Development: Utilized in academic and industrial labs for exploring new organosilicon chemistry and material science applications.

Quality Control

Our Methylethylchlorosilane is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC assay and impurity profiling, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific parameters is provided with each 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 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, oxidizers, and water.
