Description

Chloromethyldimethyl-n-Butylsilane is a versatile organosilicon compound featuring a reactive chloromethyl group. This chemical is a crucial intermediate in the synthesis of specialty silicone polymers and serves as a key building block for surface modification agents. It is primarily utilized by manufacturers in the silicone industry, pharmaceutical intermediates sector, and advanced materials research who require precise functionalization and controlled reactivity.

Application

• Silicone Polymer Synthesis: Acts as a functional monomer for introducing chloromethyl groups into silicone backbones, enabling further cross-linking or chemical modification.
• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces to alter their hydrophobicity, adhesion, or compatibility with organic matrices.
• Pharmaceutical Intermediates: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs) and drug delivery system components.
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter and cross-linking agent in high-performance silicone-based adhesives and sealants.
• Release Coatings: A precursor for creating silicone release liners used in labels, tapes, and packaging materials.
• Research & Development: Employed in academic and industrial R&D for developing novel organosilicon compounds and hybrid materials.

Quality Control

Our Chloromethyldimethyl-n-Butylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee compliance with 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 (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases, oxidizing agents, and sources of ignition.
