Description

n-(2-Hydroxyethyl)-n-(3-Hydroxypropyl)-p-Toluenesulphonamide is a specialized sulfonamide derivative featuring dual hydroxyl functionalities. This unique structure makes it a valuable intermediate and functional additive, offering a combination of solubility and reactivity. It is primarily sought after by manufacturers in the polymer, pharmaceutical, and specialty chemical industries for applications requiring hydrophilic modification and controlled reactivity.

Application

• As a key monomer or chain extender in the synthesis of polyurethane dispersions (PUDs) and other water-borne polymers.
• Utilized as a reactive intermediate in pharmaceutical synthesis, particularly for introducing sulfonamide groups.
• Acts as a plasticizer and compatibilizer in various polymer formulations to improve flexibility and processing.
• Employed in the production of specialty surfactants and emulsifiers due to its amphiphilic nature.
• Serves as a building block for UV-curable resins and coatings, contributing to enhanced adhesion and film properties.
• Used in research and development for creating novel materials with tailored hydrophilic-lipophilic balance (HLB).
