Description

2-(4-Chlorosulphonylphenyl)Ethyl Trichlorosilane in Methylene Chloride is a specialized organosilicon reagent, supplied as a solution for enhanced stability and handling. This compound is a critical intermediate for introducing a reactive silane moiety linked to a chlorosulfonylphenyl group, enabling surface modification and covalent bonding in advanced materials. It is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where precise functionalization is required.

Application

• Surface Modification Agent: Used to functionalize glass, silica, and other inorganic surfaces to create specific binding sites or alter surface properties.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug conjugates.
• Chromatography Media: Employed in the manufacture of high-performance liquid chromatography (HPLC) stationary phases and affinity chromatography supports.
• Polymer & Resin Synthesis: Acts as a cross-linking agent or a monomer for creating specialty silicones and hybrid organic-inorganic polymers.
• Agrochemical Synthesis: Utilized in the development of advanced pesticides and herbicides requiring specific silane functionalities.
• Adhesive & Coating Formulations: Enhances adhesion to difficult substrates by promoting chemical bonding at the interface.
• Bioconjugation & Sensor Development: Facilitates the immobilization of biomolecules (e.g., proteins, DNA) onto sensor surfaces for diagnostic applications.
