This chemical is primarily used as a surface modification agent in various industrial applications. It is commonly employed to functionalize surfaces, particularly glass, silica, or other inorganic materials, to introduce chlorosulphonyl groups. These modified surfaces are then used in the development of specialized coatings, adhesives, or sensors. The compound is also utilized in the synthesis of advanced materials, such as hybrid organic-inorganic polymers, where it acts as a coupling agent to enhance bonding between different phases. Additionally, it finds application in the preparation of chromatographic stationary phases, improving the separation efficiency of analytical methods. Its reactivity with hydroxyl groups makes it valuable in creating tailored surfaces for specific chemical or biological interactions.
