Description

3,6,9,12,15,21,24,27,30-Decaoxadotriacontane-1,32-Diamine is a high-purity, linear polyether diamine featuring a long, flexible chain of ethylene oxide units terminated by primary amine groups. This unique bifunctional structure is critical for synthesizing specialized polymers and surfactants with tailored properties. It serves as a key building block for advanced material scientists and formulation chemists in industries requiring precise molecular architecture.

Application

• Polymer Synthesis: Acts as a chain extender or curing agent for polyurethanes, polyureas, and epoxy resins, imparting flexibility and hydrophilicity to the final polymer network.
• Surfactant & Detergent Intermediate: Used to produce non-ionic and cationic surfactants with excellent wetting, emulsifying, and dispersing properties for industrial and institutional cleaners.
• Pharmaceutical Excipients: Employed in the synthesis of polymeric carriers for drug delivery systems, where its biocompatibility and tunable solubility are advantageous.
• Personal Care Formulations: Serves as a precursor for conditioning agents and viscosity modifiers in hair care and skincare products.
• Adhesive & Sealant Modifier: Incorporated to enhance the adhesion, flexibility, and moisture resistance of high-performance adhesives and sealants.
• Textile & Fiber Treatment: Utilized in the production of antistatic agents, dye leveling agents, and fabric softeners for synthetic fibers.
• Oilfield Chemicals: Applied in the synthesis of demulsifiers and corrosion inhibitors for use in crude oil processing and drilling fluids.
• Research & Development: A valuable reagent for academic and industrial R&D focused on novel dendritic polymers, hydrogels, and advanced functional materials.
